Does Costco Price Match?

Verified 2026

Costco does not price match any competitor, including Amazon, Walmart, or rival warehouse club Sam's Club — but it will refund the difference within 30 days if Costco itself lowers the price on an identical item.

No Competitor Matching, Even Between Warehouse Clubs

Costco doesn't compare its prices against Amazon, Walmart, Best Buy, or any other outside retailer — and notably, it won't match Sam's Club or BJ's Wholesale Club either, even though they're direct membership warehouse competitors. What Costco does offer instead is a price adjustment: if Costco lowers the price on something you bought within the past 30 days, a member can request the difference back.

Competitor price matching (Amazon, Walmart, Sam's Club, BJ's, etc.)	Not offered — Costco does not match any outside retailer
Costco's own price drops	A member can request the difference if Costco lowers the price on an identical item within 30 days of purchase

The 30-day price adjustment applies only to Costco's own price changes, not a lower price found at another retailer.
