Wikibuy tests coupon codes at hundreds of retailers with just one click! While shopping at a participating retailer, a notification from Wikibuy will appear on the cart page or checkout page—generally wherever a coupon code field is present.
When the notification above appears, click the big green "try codes" button—and watch as the codes are automatically applied.
Depending on how many codes Wikibuy finds, it should only take a few moments for all coupons to be tested. Once all codes are tested, Wikibuy automatically applies the best coupon code from the bunch and displays the total amount of savings.
With the above example, you can see that 2 codes worked and $16.25 is saved within 2.20 seconds of testing coupon codes.
