How to save at Costco
Here are our top tips for saving at Costco:
- Always check this page first - we update Costco coupons daily and list the highest-discount offers at the top.
- Sign up for the Costco newsletter - first-order discounts of 10-15% are common and arrive in your inbox within minutes of signing up.
- Time your purchase to sale events - Costco runs deeper discounts during seasonal sales than any everyday coupon offers, so save bigger purchases for those windows.
- Stack codes with cashback - if your credit card or shopping browser extension offers cashback at Costco, layer it on top of any coupon code you use here for extra savings.
- Hit the Costco clearance section - clearance items often qualify for additional percent-off codes, doubling your savings on already-discounted prices.
