Love it. I save good amount of %!

This add on is new to me, but it looks like a reputable new app to help save money on items.

Actually Good

It popped up stating I could earn a reward even though none of the codes worked when I was shopping on Amazon but the popup disappeared and when I reopened the extension on the same page it wouldn't display it.

good, a little more involved than honey, but tends to have codes that they dont

Very cool A+++

mmmm
