Shoppers can find Costco coupons available on the Costco website, through the company app or by visiting warehouse locations, according to Costco's website. Current members typically receive a coupon book in the mail.
The coupon book offered by Costco has a valid-through date, so members should ensure the coupons have not expired before they attempt to redeem them. The Costco app is another way that shoppers can redeem current coupons, according to Costco's website. Some offers are instant savings, which means that all shoppers receive the promotional price, whether or not they present a coupon. Other offers require that shoppers present a printed coupon or show the Costco app on their phone to the cashier upon checkout to receive the offer.
