The #1 Way to Save at Costco

Most people look for Costco coupon codes or wait for sales. But the smartest shoppers use a different strategy: buy discounted gift cards before they shop.

Here's how it works: you buy a Costco gift card at 4% below face value (pay $96 for $100). Then you use that gift card for your next purchase. The card works exactly like cash — online at costco.com or in any Costco location.

The best part? You can stack this with any existing promotion. If Costco is running a 20% off sale, you get the sale price plus your gift card discount. That's real savings that add up fast.
