Costco shopping calendar 2026 2027 what to buy every month when to buy it why timing is everything complete month-by-month guide what to buy when clearance hits which events to plan around seasonal timing secrets members use

Timing is everything at Costco — and the member who understands the warehouse's seasonal rhythm captures a dramatically different financial result from the same membership as the member who shops reactively, visit by visit.

The strategic Costco member's most powerful tool is not the membership card itself. It is the knowledge of when each category reaches its lowest annual price, when each seasonal event's best items arrive at full inventory, and when each clearance window opens for the purchases that need to happen now before the opportunity disappears for another year.

This guide is the complete Costco shopping calendar for the year ahead — organized month by month from October 2026 through September 2027, covering what to prioritize in each month, which events create commercial urgency, and which purchases are best deferred to the optimal pricing window rather than made at the moment the need arises.

The member who reads this guide and builds it into their household shopping strategy will capture savings opportunities that the reactive shopper misses consistently — not because the reactive shopper lacks access, but because timing creates the difference between the best price and the price that was paid without knowing the best one was coming.

October 2026: The Transition Month

What to Buy

Halloween candy and treats: the Halloween Treats Sale runs October 22-31 with 40 to 50 percent off candy and remaining seasonal items. Stock up on candy for this year's trick-or-treat — and if flexibility exists, purchase next year's Halloween candy now for deep freezer storage at the best annual price.

Holiday Savings Book items: the Holiday Savings Book arrives around October 19. Electronics and toys — the fastest-selling categories — should be purchased in the first two weeks of the book's availability. Later purchases risk finding the best items sold out.

Summer clearance: outdoor furniture, patio equipment, kayaks, and summer sporting goods hit their deepest annual markdowns in October as the warehouse floor converts to holiday merchandise. This is the last opportunity until spring 2027.

What to Wait On

Christmas gifts beyond the Holiday Savings Book items: Wave 1 launches October 30 at full inventory. Christmas shopping before October 30 means shopping depleted September inventory rather than the full Wave 1 selection. Wait for October 30.

November 2026: The Holiday Peak Month

What to Buy

Christmas merchandise at full selection: the two-week window following October 30's Wave 1 launch is the highest-selection moment in the holiday calendar. The specific items that generate the most member enthusiasm — novelty trees, statement decorations, the most popular gift configurations — sell through before Thanksgiving. Buy before November 15 for the best selection.

Thanksgiving provisions: Costco's complete Thanksgiving offering — turkey options (whole birds, boneless turkey breast, the complete precooked dinner package), pies ($21.99 for the pumpkin, available through the season), sides, charcuterie, and sparkling wines — is at its fullest inventory in early November. The member who shops the first week of November has the full selection; the member who shops the week before Thanksgiving navigates depleted inventory in the categories that matter most.

The Kirkland Signature Pumpkin Pie: the most beloved seasonal item in the Costco bakery — a 12-to-14-person pumpkin pie at $21.99 — is available from early November through the Thanksgiving period. Members who want to purchase multiple pies (for multiple gatherings or for freezing) should shop early in the month when the bakery's production is at peak and the selection is full.

What to Wait On

Spring merchandise: spring garden items, outdoor furniture, and spring apparel will not appear in the warehouse until February or March. Attempting to purchase spring items in November results in unavailable inventory rather than early-bird access.

December 2026: The Gift and Holiday Month

What to Buy

Remaining Holiday Savings Book items (through mid-December): the Holiday Savings Book's promotional window typically runs through mid-to-late November, but the specific items it featured should be purchased before the book expires. Any remaining items in the book's final days represent the last opportunity to access those specific savings.

Wave 2 Christmas merchandise: Costco typically releases a second wave of holiday merchandise in late November or early December — replenishing sold-out items and introducing additional gift configurations that were not in Wave 1. Check the warehouse in early December for the Wave 2 additions.

Holiday food and entertaining: December brings Costco's most complete holiday entertaining selection — specialty cheeses, premium charcuterie, holiday dessert items, sparkling wine cases, and the Sanders Sea Salt Caramels that the holiday community considers essential. These items do not peak in availability until December.

Electronics gift purchases: any electronics gift purchases should happen November 1 through December 31 to take advantage of the extended holiday return policy — the 90-day clock starts December 25 rather than the purchase date. This provision makes December electronics purchases risk-free from a gift recipient evaluation perspective.

What to Wait On

Holiday decor: by early December, the most popular holiday decor items (statement trees, novelty decorations, specific ornament sets) are likely sold through. December holiday decor purchases navigate what remains rather than the full selection. If specific items are needed, check Costco.com for online-only inventory that may supplement the depleted warehouse selection.

January 2027: The Hidden Best Month for Savings

What to Buy

Post-Christmas clearance: the post-Christmas clearance period runs from December 26 through mid-January — seasonal items often get marked down to make room for the next season, with the deepest discounts typically rolling out beginning December 26 and into the new year. Members can save up to 90 percent on holiday decor, Christmas gifts, and seasonal items for next year's use.

The January clearance window is the single best annual opportunity for members who plan ahead — purchasing Christmas wrapping paper, holiday decorations, seasonal entertaining items, and gift sets for next year's holidays at 50 to 90 percent off this year's retail price.

Winter clothing clearance: any remaining winter clothing — fleece, thermals, outerwear — begins clearing in January as the buyer team prepares for spring arrivals. The member who needs winter clothing for practical use (rather than fashion currency) finds the January pricing dramatically below what the same items cost in October and November.

Furniture and home goods: Costco often introduces its first wave of new furniture and home goods in January — the New Year home refresh category that represents the member community's post-holiday desire for domestic renewal. This is an emerging buying opportunity rather than a clearance one.

What to Wait On

Outdoor and patio: the spring outdoor merchandise will not arrive until February or March. January outdoor section is either clearance from the fall (already heavily picked over) or empty. Wait for March.

February 2027: The Valentine's Month and Pre-Spring Window

What to Buy

Valentine's Day jewelry: the Valentine's Day jewelry promotion — typically spend $1,499 or more on qualifying jewelry items, save $250 off — is the single annual event that generates the most jewelry community discussion and the most first-time Costco jewelry purchases.

The promotional savings apply to GIA-certified diamond rings, earrings, and necklaces at institutional Costco pricing — making February the optimal month for any significant jewelry purchase that can be timed to the Valentine's window.

Valentine's Day food and entertaining gifts: the chocolate selections, wine and sparkling wine configurations, and specialty food gift sets that the Valentine's Day commercial window generates appear in late January and early February.

Pre-spring inventory preview: the first spring merchandise begins arriving in late February — patio furniture, outdoor plants, spring gardening supplies, and seasonal clothing — at full original pricing rather than the clearance pricing that the prior year's equivalent items reached in October. The member who sees a specific patio furniture configuration in February that they want for spring entertaining should purchase now rather than waiting for summer and risking a sold-out condition.

March 2027: The Spring Launch Month

What to Buy

Outdoor and patio furniture at spring debut: March marks the full spring patio furniture arrival — the complete selection of outdoor seating, dining, and entertaining furniture at the warehouse's annual pricing. The most popular configurations sell through between March and June; waiting until summer risks the specific items already sold out.

Garden and plants: the spring rose event (featuring Heirloom Roses at institutional pricing) typically arrives in April or May, but the preparatory garden items — planters, garden tools, soil amendments, seeds — begin arriving in March. The member planning a spring garden should visit in March to assess the available selection before April's peak gardening season.

Spring clothing: Costco's spring clothing arrival — lightweight layers, activewear, and spring basics — appears in March at full seasonal pricing. The member who needs specific spring clothing items (children's sizes in particular, which sell through quickly) should shop March rather than waiting for summer.

April 2027: The Flower and Outdoor Living Peak

What to Buy

Heirloom Roses online event: the Costco online climbing rose event — featuring Heirloom Roses at below-nursery institutional pricing — typically runs in April or May and sells through quickly. Members who discovered this guide's garden section know to monitor Costco.com in April for the event's appearance.

Outdoor living equipment: patio heaters, outdoor entertainment systems, and outdoor kitchen equipment arrive in April for the spring outdoor living season. The member who is planning an outdoor space upgrade should purchase in April when selection is at its fullest — not in July when the best configurations have already sold through.

May 2027: The Pre-Summer Peak

What to Buy

Memorial Day weekend items: Costco's Memorial Day commercial window — grilling equipment, outdoor furniture, coolers, summer beverages, and entertaining food items — represents the transition from spring to summer pricing. Some items generate their deepest spring discount in the Memorial Day promotional window.

Summer road trip provisioning: the pre-summer Costco run for road trip essentials — the water cases, the trail mix packs, the beef stick boxes, the cold brew coffee multi-packs — is most efficiently accomplished in May when summer inventory is full and the road trip season is imminent.

June — August 2027: The Summer Peak Season

What to Buy

Summer items at peak selection: outdoor entertaining equipment, summer beverages, pool and beach supplies, and the institutional food items that support summer cooking are all at their peak selection in June through August. This is the period to buy summer items — not to defer them to a clearance window that will have depleted selection.

Fall clothing early-arrival in August: Costco's fall clothing — the Kirkland Signature heavyweight fleece, fall basics, outerwear — arrives in August at full seasonal pricing. The member who needs specific fall clothing in specific sizes (particularly children's and family wardrobes) shops August when selection is fullest.

What to Wait On

Summer clearance: the August 15 – September 15 window is when summer merchandise begins clearing at 40 to 60 percent off. The member who can defer summer recreational equipment purchases to mid-August captures significantly better pricing than the June purchase. The risk: specific items sell through in the clearance window faster than at full price, so deferring requires flexibility on specific models and configurations.

September 2027: The Strategic Re-Start

What to Buy

Fall finds and new September arrivals: the September new items guide documents what arrives each year — the pretzel bun sandwiches, the returning member favorites, the fall bakery items, and the first Halloween merchandise. The member who shops September in the first week of the month captures the earliest and fullest inventory of fall arrivals.

Summer clearance final window: the September 1-15 period is the tail end of the summer clearance window — the deepest discounts on remaining summer merchandise before the fall and holiday transition consumes the warehouse floor space.

Early holiday preparation: as the September-to-October guide communicates, September is the earliest month that Christmas merchandise begins appearing. The member who discovered a specific holiday item in October 2026 and is hoping for its return in September 2027 should begin monitoring the warehouse floor in the first weeks of September.

The two best months for overall value: January (holiday clearance) and October (summer clearance + Halloween Treats Sale + Holiday Book arrival simultaneously).
