Product Rotation Schedule: When Items Cycle and Prices Drop

Quick answer: Costco doesn't publish a fixed rotation calendar, but its inventory follows predictable patterns tied to seasons, the Kirkland Signature refresh cycle, and treasure-hunt clearance items marked with special codes. Electronics and seasonal goods (patio furniture, holiday items, back-to-school supplies) rotate on 8-12 week cycles, while core Kirkland Signature products get reformulated or repackaged once or twice a year. Watching price codes ending in 97 or 88, plus tracking your own purchases for 30 days, is the most reliable way to catch a markdown before it disappears.

Key takeaways

• Costco operates on a treasure hunt model — about a third of warehouse floor space is dedicated to rotating, limited-time items rather than a fixed planogram, a merchandising strategy Costco has described in its own investor materials.
• Item numbers ending in .97 or .88 typically signal manager-initiated clearance markdowns meant to move stock fast, while a 1 at the end of the item number often flags a discontinued product.
• Seasonal resets cluster around four windows each year: late winter (spring/garden), early summer (patio/outdoor), late summer (back-to-school/fall), and October–November (holiday).
• Costco's price adjustment policy gives members 30 days from the purchase date to claim a refund if an item drops in price, according to Costco's published member policies — which is exactly the window a rotation schedule helps you plan around.

What Is Costco's Product Rotation, Exactly?

Costco's product rotation is the ongoing cycle of items entering and leaving warehouse shelves, driven by seasonal demand, vendor contracts, and the company's deliberate strategy of stocking limited batches of non-food merchandise. Costco calls this the treasure hunt approach — a mix of steady staples (toilet paper, Kirkland Signature olive oil) and constantly changing one-off deals (a pallet of luggage one month, patio heaters the next).

Unlike a grocery store that restocks the same 40,000 SKUs every week, Costco intentionally limits its selection to roughly 4,000 items company-wide, a figure Costco has cited publicly to explain its lean-inventory model. That smaller footprint means each item has to earn its shelf space, and anything that doesn't sell through fast gets marked down and replaced.

This matters for your wallet because rotation and price drops are linked. When Costco decides to phase out a product — whether it's last season's stand mixer color or a TV model being replaced by a newer version — the price usually drops before the item vanishes for good. That drop is exactly the kind of event that triggers eligibility for a price adjustment refund if you bought it recently.

How Often Do Items Actually Rotate?

It depends on the category, and Costco doesn't publish exact intervals, so the timeframes below are patterns shoppers and retail analysts have observed rather than official figures.

Category	Typical rotation pattern	What drives it
Seasonal/patio/holiday	4 major resets per year	Calendar seasons, holiday demand
Electronics (TVs, laptops, tablets)	Every 8-12 weeks	New model releases, vendor promotions
Kirkland Signature packaged goods	1-2 times per year	Formula or packaging updates
Apparel	6-8 week cycles	Limited batch buying, no restocks of same style
Clearance/treasure hunt items	Continuous, no fixed schedule	One-time vendor buys, overstock
Tires	Ongoing with periodic promotional pricing	Manufacturer rebates and seasonal demand

Electronics move the fastest because manufacturers release new models on their own schedules, and Costco negotiates limited-run pricing that expires once the next generation ships. If you've ever noticed a laptop's price drop by $150 a few weeks after you bought it, that's usually the rotation clock ticking down to a model swap — a scenario we cover in more detail in How Costco Price Adjustments Work on Black Friday, since Q4 is when electronics rotation and holiday pricing overlap the most.

Tires follow a different logic. Costco Tire Center pricing shifts around manufacturer rebate periods rather than a strict seasonal calendar, and the refund rules for tires work differently than for general merchandise — we broke down the specifics in Costco Tire Price Adjustment: How the Refund Rules Work.

What Do the Price Codes on Costco Tags Mean?

The number at the end of a Costco price tag tells you why an item is priced the way it is, and it's the fastest way to spot something about to disappear. This isn't an official published Costco policy — it's a pattern long documented by Costco shoppers and retail bloggers — so treat it as a helpful signal, not a guarantee.

• Price ends in .99 — regular, full-price item with no markdown.
• Price ends in .97 — a manager-initiated markdown, often the first clearance step.
• Price ends in .88 — a deeper, final clearance markdown before the item is discontinued.
• Item number ends in a 1 (like an asterisk-marked SKU) — the product is being discontinued and won't be reordered once stock runs out.
• An asterisk (*) in the corner of the tag — this item won't be restocked; what's on the shelf is what's left.

If you see both a .97 or .88 price and an asterisk on the same tag, that's about as clear a signal as Costco gives that the item is on its way out — and possibly headed for an even deeper markdown before it's gone.

Don't skip this: if you bought something at full price and later spot it with a .97 or .88 tag, check your receipt date immediately. Costco's price adjustment window is 30 days from purchase, according to Costco's official return and adjustment policy — miss that window and the drop no longer qualifies for a refund.

When Do Seasonal Resets Happen?

Costco resets its seasonal sections roughly four times a year, and knowing the rough windows helps you avoid buying something right before it's marked down.

• Late January–March: Winter clearance gives way to spring and garden items — patio furniture, planters, outdoor power equipment.
• May–June: Early summer reset brings pool supplies, grills, and outdoor recreation gear, with early-season patio items sometimes marked down as newer sets arrive.
• August–September: Back-to-school supplies phase out as fall and early holiday merchandise (Halloween decor, early Christmas items) starts appearing on shelves.
• October–November: The biggest reset of the year — holiday décor, toys, and gift-focused electronics take over end-caps and the center aisles, often tied to Black Friday-style promotional pricing.

August in particular is a transition month worth watching closely. Back-to-school stock gets marked down to clear space, while early holiday shipments start trickling in — which is exactly why you'll see roundups of new August arrivals alongside clearance signage in the same aisle. If you bought a folding chair or a set of school supplies in July, check the shelf tag again before the 30-day window closes.

Does the Rotation Schedule Work the Same Way in Canada?

Mostly yes, but with some differences worth knowing if you shop at Costco Canada. Seasonal categories follow similar timing (patio in spring, back-to-school in August, holiday in fall), since Costco Canada sources many of the same vendor contracts as the US warehouses. But regional demand shifts things — winter gear rotates in earlier and stays longer in Canadian warehouses given the climate, and some US-exclusive electronics promotions don't appear north of the border at all.

The bigger difference isn't the rotation itself — it's what happens after a price drops. Costco Canada's price adjustment policy and refund process have some meaningful distinctions from the US version, which we cover fully in Costco Canada vs. US: How Price Adjustments Differ. If you shop both sides of the border, or you're a US member visiting a Canadian warehouse, it's worth reading before you assume the same 30-day rule applies identically.

How Can You Actually Use This Schedule to Save Money?

The rotation schedule only helps if you track your own purchases against it, because Costco doesn't notify you when something you bought goes on clearance. Here's a practical checklist for turning this into real savings:

• Save every Costco receipt (paper or digital) for at least 30 days after purchase.
• Check shelf tags for .97 or .88 endings on anything you bought in the last month.
• Note the item number on big-ticket purchases — TVs, tires, appliances — since these rotate fastest and carry the biggest dollar swings.
• Watch for asterisks or "while supplies last" signage near items you own, since that's your cue the price may drop again before it's gone.
• Set a personal reminder around week three after any purchase, so you're not relying on memory as the 30-day window closes.
• Compare warehouse-specific pricing if you shop at more than one location, since clearance timing can vary warehouse to warehouse.

Doing this manually works, but it's easy to lose track of ten or fifteen receipts across a busy month — which is the exact gap CostRefund was built to close. The app scans your receipts, tracks each eligible item against the 30-day window automatically, and sends an alert the moment something you bought drops in price, so you're not the one staring at shelf tags trying to remember what you paid in July.

If you've never calculated what missed price drops cost you over a year of shopping, the numbers add up faster than most people expect — we ran the math in The True Cost of Not Tracking Costco Price Drops: A Year in Numbers.

Ready to stop guessing when your Costco haul might drop in price? CostRefund tracks every eligible receipt for 30 days, sends instant alerts on price drops, and helps you claim refunds before the window closes — for both Costco US and Costco Canada shoppers.
