Occasionally, you'll see a retailer's ad pop up with a Cashback logo appended to the corner. When that happens, it's game time.

Click on the advertisement to jump to the retailer's results for whatever it is you searched for. But here's the kicker--you're locked in to the percentage rate for the entire store.

You'll receive the same Cashback refund even though your path into the merchant's page had nothing to do with your final purchase.
