The working discount code, ready before you reach checkout.

A browser extension that tests discount codes for you while you shop.

You know how it goes. You get to the payment page, open another tab, and paste in code after code until one of them sticks. Usually none of them do. The discount expired months ago, or it never applied to what is in your cart to begin with.

Liberate Green does that work early. While you are still looking at a product, it gathers the codes that might apply to the store and tries each one against the item you are actually looking at, at its real price and quantity. By the time you get to checkout it already knows which code wins, what it takes off, and whether anything is in the way.

If nothing works, it says so, instead of letting you find that out one failed attempt at a time. If a code almost works, say you are a few dollars under a minimum spend, it tells you that too, and you can decide whether it is worth it.
