Amazon’s 2026 Big Spring Sale ended March 31. Costco’s offers are separate promotions, and some listed discounts may still be available: for example, Costco listed an 18-piece Snapware Pyrex glass food storage set for $19.99 after $5 off through October 11, 2026. Check the current listing, your Costco channel and local inventory before buying; these offers are not a live Amazon-versus-Costco price comparison.
Is Amazon’s Big Spring Sale still running?
No. Amazon’s FAQ dates the 2026 Big Spring Sale from March 25 through March 31, 2026, ending at 11:59 p.m. PDT on March 31. The event was open to all customers and included Prime-exclusive deals. Amazon described offers across more than 35 categories, with advertised maximum discounts of up to 35% off Kitchen, 30% off Lawn & Garden and 25% off Home. Those were promotional ceilings for the past event, not current prices or typical savings. Amazon’s Big Spring Sale FAQ and its deal roundup provide historical details; neither establishes that those prices remain available.
Costco offers listed for fall 2026
Costco’s weekly offers page listed the following examples with offer dates spanning September and October 2026. Treat them as dated listings, not a guarantee of stock at a particular warehouse or a statement that every channel carries the same offer. The Snapware and T-fal offers were due to end October 11, so check the live listing before relying on them.

How to compare a Costco offer with an Amazon listing
The available retailer pages do not establish current Amazon prices for equivalent Costco products, so they do not support naming a price winner. Before deciding, compare the same item or genuinely equivalent specifications, then calculate the final cost and confirm the offer applies to you.
- Product and quantity: Match the model, included pieces, size and pack count. A set with more pieces is not automatically a better value if the pieces differ.
- Delivered cost: Compare the total after shipping or delivery charges and taxes where known, rather than comparing one retailer’s shelf price with another’s delivered price.
- Eligibility and channel: Check whether membership is required and whether the price applies to Costco.com, a regular warehouse or a Business Center. Costco Business Center promotions can have separate terms.
- Dates and stock: Confirm the deal is active, note its expiration and check availability for your location. Online listings do not guarantee local warehouse inventory.
- Returns and warranty: Review the terms for the particular item at both retailers; do not assume they are identical.
Costco price adjustments and retailer price matching
Costco says it does not match prices from other retailers. Its separate price-adjustment policy applies only to qualifying Costco.com purchases: a Costco price reduction within 30 days may qualify, subject to item limits and exceptions. For an item with specific sale dates, submit a request during the promotion and within 30 days of purchase; Costco says requests after the promotion ends may be denied. The policy also excludes matching Costco warehouse prices for Costco.com purchases and reserves Costco’s discretion to deny requests. Read the full Costco.com price adjustment terms.

What to know about Costco Business Center savings
Costco Business Center’s separate Savings Event page listed an instant-savings window of September 21–October 18, 2026. Its terms say savings apply to regular walk-in or delivered prices, selection varies by location, quantities are limited, and a valid Costco membership is required. The page also describes delivery and promotion conditions and says rain checks are not issued for out-of-stock items. These terms apply to that Business Center event, not automatically to regular warehouses or Costco.com. Check the Business Center Savings Event page and the relevant location or delivery listing.
