Offer terms
What is a qualifying online purchase? To make a qualifying online purchase, you must click the button below, and then complete a purchase at the selected merchant’s site, in the window opened by the Capital One Offers tile, within 24 hours. If an offer specifically lists an available coupon on this page, you may use it on the merchant’s site, subject to any coupon-related conditions that we display, but you must do so within 24 hours of activating the offer and during the same open browser session triggered by your offer activation. Use of any other coupons, cash back, or promotional websites after selecting an offer and before making a purchase will invalidate your offer. Use of VPNs and ad blockers may also invalidate your offer. Online purchases made on websites without first being redirected by a Capital One Offers tile are not qualifying online purchases. How is the payout calculated? The payout for qualifying online purchases is calculated using the subtotal amount of your eligible purchase, which is calculated after any eligible coupons are applied, and excludes taxes, shipping, credits, and other fees. A payout earned through this offer is in addition to any rewards regularly earned with your card. If you return or cancel an otherwise qualifying purchase, you are not eligible for a payout. Payouts for subscription services are only awarded to new customers in their first billing period after the merchant has confirmed your payment has processed. Payouts are not available on trial memberships, unless otherwise stated.
