This is the first coupons/deals add-on which seems really to have fully moved into the third decade of the 21th Century. It operates rapidly and efficiently.

Coupons! Easy and Simple.

This extension has frequent updates, but its too bad I can't get it to do anything. I've gone to a handful of major shopping sites, gone to multiple items' detail pages, added to shopping carts, gone to checkout... Nowhere during the process does anything pop up, and nor does anything even happen when I click on the extension's icon. Their website looked promising. Oh well.

It actually works!, without the ever annoying nags present with other code-discount finders.

Works the best of all coupon extensions. Has working codes for most stores, super easy to use too.
