Costco Price Drops: When Seasonal Items Go on Sale

Quick answer: Costco marks down seasonal items on a predictable rotation — usually 4 to 8 weeks after peak demand, and often right after the holiday it's tied to. Halloween décor drops in early November, Christmas items in late December, and lawn and garden gear starts falling as early as July. If you bought within the last 30 days and the price drops, Costco's price adjustment policy lets you claim the difference in both the US and Canada.

Key takeaways

• Costco's price adjustment window is 30 days from purchase in both the US and Canada, but Costco Canada requires the original receipt and item barcode for in-store adjustments, per Costco Canada's published return policy.
• Seasonal clearance timing follows the calendar, not the inventory: Halloween candy and décor typically mark down starting November 1, while Christmas trees and lights often drop the week after December 25.
• Lawn and garden, patio furniture, and swimwear tend to see the steepest cuts in July and August, once warehouses start clearing floor space for back-to-school and fall goods.
• Costco does not publish an official markdown calendar — timing varies by warehouse, region, and how fast inventory moves, so treat all dates here as general patterns, not guarantees.

Why does Costco mark down seasonal items at all?

Costco drops prices on seasonal goods because warehouse floor space is limited and inventory has to keep moving. Unlike a typical retail chain with deep backroom storage, Costco's model depends on high turnover — new pallets need room, and last season's patio sets or holiday inflatables are standing in the way.

This creates a fairly consistent pattern:

• Inventory rotation — Costco plans floor resets around upcoming categories (fall goods replace summer goods, holiday goods replace fall goods), and anything left over gets discounted to clear it out fast.
• Demand cliffs — seasonal items don't fade slowly; demand for Halloween costumes basically stops on November 1. Retailers mark down hard right after the cliff rather than let items sit.
• Regional variation — a warehouse in Phoenix clears patio furniture on a different timeline than one in Minneapolis, because local buying seasons don't match.
• Buyer decisions at the warehouse level — individual Costco locations have some discretion over markdown timing, so the same item might drop two weeks apart at two different warehouses.

None of this is published as an official schedule. Costco doesn't release markdown dates the way some retailers publish a "clearance calendar." What follows is a pattern based on how seasonal retail categories behave, not a guarantee for any specific item or location.

Which seasonal categories drop the most, and by how much?

Holiday décor and outdoor living gear see the deepest cuts because they're the most calendar-locked categories Costco carries. If an item is only useful for six weeks a year, it has to be discounted hard once that window closes — there's no "wait for next month" demand to prop up the price.

Category	When it drops	Why
Halloween décor & candy	Early November	Demand ends abruptly on Nov 1
Christmas trees, lights, ornaments	Late December–early January	Post-holiday clearance to reset for spring
Lawn & garden, patio furniture	July–August	Warehouses clear floor space for fall
Winter coats, boots, snow gear	February–March	End of cold-weather selling season
Swimwear & beach supplies	Late July–August	Summer demand tapers before school starts
Back-to-school supplies	Early September	Short selling window closes fast

The size of the markdown depends on how much unsold inventory is left. A hot item that sells through by the holiday might never get marked down at all — it just disappears. A slow mover might see two or three price cuts stacked within a few weeks. That's exactly the kind of item worth tracking closely, since each cut can qualify for a separate adjustment if you're still inside your 30-day window.

When exactly should I expect prices to drop, month by month?

Here's a rough month-by-month view of what typically clears, based on general seasonal retail patterns:

• January — Christmas leftovers finish clearing; winter gear starts its first markdown.
• February — Valentine's items drop right after the 14th; winter coats and boots see deeper cuts.
• March — Snow gear clearance continues; early spring/garden items start appearing at full price.
• April — Easter décor and candy drop right after the holiday; spring gardening supplies ramp up.
• May — Patio and outdoor furniture arrive at full price; Mother's Day items clear fast.
• June — Early summer swimwear and pool supplies still full price; graduation items clear.
• July — Patio furniture and lawn/garden gear begin their biggest markdown window.
• August — Swimwear, beach supplies, and remaining garden stock drop hard before back-to-school sets in.
• September — Back-to-school clearance begins; Halloween stock arrives at full price.
• October — Halloween items stay at full price until the last week, then start dropping fast.
• November — Halloween clears in the first two weeks; Christmas stock is full price, though Black Friday and the Costco coupon book bring temporary markdowns worth watching alongside seasonal clearance.
• December — Christmas décor holds price until after the 25th, then drops sharply into January.

Don't skip this: the 30-day price adjustment clock starts on your purchase date, not the day the sale starts. If you bought a patio set on July 1 and it drops on July 25, you're still covered — but if it drops August 5, you've already missed the window.

Does the price adjustment policy work the same in Canada as the US?

Mostly yes, but the paperwork differs. Both Costco US and Costco Canada honor a 30-day price adjustment window from the date of purchase, but Canada's process leans more heavily on having your physical receipt and the item's barcode on hand for in-store claims, according to Costco Canada's published policy.

A few practical differences worth knowing:

• Holiday timing shifts. Canadian Thanksgiving falls in October, not November, which can shift when fall décor and harvest items start clearing compared to US warehouses.
• Currency and pricing differences mean a markdown percentage that looks small in USD can look different in CAD, so compare the actual dollar difference, not just the percentage.
• Regional clearance speed varies more in Canada simply because there are fewer warehouses spread across a larger area, so a markdown might hit a Costco in Ontario weeks before one in Alberta.
• Membership terms are consistent across both countries for the adjustment window itself — it's the claim process and required documentation that diverge slightly.

How do I actually catch these drops before the window closes?

You catch them by tracking your purchase date and checking prices regularly — manually, or with an app that does it for you. Thirty days goes by fast, especially for a Halloween buy made in early October that you might forget about by the time the holiday actually hits.

A practical checklist for seasonal shopping:

• Save every receipt, digital or paper, the day you buy a seasonal item.
• Note the exact purchase date somewhere you'll actually check — a calendar reminder works better than memory.
• Check the item's price weekly during known clearance windows (see the month-by-month list above).
• Compare warehouse floor prices, not just online listings, since Costco.com and in-store pricing can differ.
• File your adjustment claim as soon as you spot a drop — don't wait for the 30 days to nearly run out.
• Keep your item barcode or SKU handy, especially for Canadian claims where it's commonly requested.

This is essentially what CostRefund automates: scan your receipt once, and it tracks every item's 30-day window and pings you the moment an eligible price drops, instead of you manually rechecking prices during clearance season. If you're the type who likes watching your running savings total climb — or comparing it against friends on a leaderboard — that tracking turns into something closer to a game than a chore.

One more edge case worth knowing: if an item you bought gets marked down and then marked down again within your 30-day window, you're generally only owed the difference from your original price to the lowest qualifying price during that window — not multiple stacked refunds. Confirm the specific math with the warehouse or member services if a multi-drop situation comes up.

For general item tracking beyond just seasonal goods, How to Read a Costco Receipt Item Code for Price Drops is worth a look — knowing your item numbers makes checking for drops much faster.

Seasonal clearance is one of the few predictable patterns in Costco pricing, but predictable doesn't mean automatic — nobody refunds you without a claim. Set a reminder, check back during the windows above, and don't let a good buy turn into money left on the table.

Ready to stop tracking this manually? CostRefund scans your receipts, watches for eligible price drops in real time, and alerts you before your 30-day window closes — in both the US and Canada.
