How Costco Coupons Worked in May 2018
In May 2018, Costco members used coupons to lower prices on selected items in stores in the United States. These offers typically targeted household staples and brand-name products, and they required a valid membership for redemption at the register. Unlike everyday low pricing, coupons were time-limited and available while supplies lasted. This overview explains how members found, qualified for, and applied these discounts in May 2018.
Eligibility and Membership Requirements
Only active Costco members were eligible to redeem coupons in May 2018. Membership types include Gold Star and Executive, and both could use coupons on qualifying purchases. Photo ID and membership card were required at checkout to verify eligibility. Coupons were non-transferable and not valid on previous purchases.
