Costco Cash Rewards from Citi are distributed annually with your February credit card billing statement. If you've signed up for paperless statements, you'll receive it via email instead.
If you need to replace your reward, you may do so by logging in to your online Citi account here: www.citicards.com.
To redeem them, simply visit your local Costco warehouse (they are valid anywhere within the U.S., including Puerto Rico). Please note that reward coupons can't be redeemed at our gas stations or online at Costco.com. However, you can redeem your coupon at any Costco warehouse towards the purchase of a Costco Cash Card, then use that card for shopping online at Costco.com or at any of our gas stations.
