About Costco Membership
New-member sign-up promotions are where a Costco Membership coupon code has the most real impact, sometimes including a bonus digital shop card for enrolling in auto-renewal. Executive Members also earn an annual 2% reward (up to $1,000) on qualifying purchases -- more of a built-in ongoing discount than something you'd apply as a code.
