About Capital One Shopping
Capital One Shopping (formerly Wikibuy) is a free browser extension and mobile app available to anyone, including non-Capital One customers. The extension surfaces lower prices at competing retailers in real time, automatically applies the best public promo code at checkout, and earns Shopping Credits on qualifying purchases at over 30,000 partner sites. Shopping Credits are redeemable only as gift cards, not cash, which makes the portal best suited to shoppers who reliably spend at a small set of supported brands.
Payout method
Gift cards (no cash payout) after the cashback balance clears the $5 minimum threshold. Cashback typically posts as pending within 3-10 business days of a tracked order and clears to payable after the retailer's published return window closes.

How Capital One Shopping stacks with promo codes
Cashback through Capital One Shopping is paid on the post-discount, pre-tax subtotal in nearly every case, which means a working DealTrackr promo code reduces the dollar amount of cashback but does not disqualify the order from the cashback program. The correct order of operations is: load the retailer page from a fresh browser tab, copy the promo code from DealTrackr, click the Capital One Shopping merchant tile to open a tracked session, complete checkout, and confirm both the discount line and the Capital One Shopping tracking confirmation are visible before submitting payment.
