This is a scam.

Me lo baje y me ahorre 10 dolares, piola

Used to be ok, but can't log in lately. The google login pop-up window stopped working. Removed the browser extension as I don't get enough savings to justify the privacy issues.

I try click on screen nothing happen so uninstalled it

Every cent counts

Doesn't let me droplist items; when I try, it requires me to choose options(such as Regular vs Special Edition on a video game), but won't let me click any options, so the button to save the item stays grayed out. I always have to go use Chrome's version of the extension to actually get anything done.

This is completely useless. You can't log in using Google - it just brings up a series of pop-up windows that go nowhere.

unbrauchbar in Deutschland, Stichproben ergaben, kann mit deutschen Bezeichnungen wenig anfangen und sucht auch nur im amerikanischen Raum, Preisangaben erfolgen immer in Dollar, egal welchen Rabattcoupon gefunden wird, Versand und Zoll frisst alles auf, gut gedacht, saumäßig durchgeführt

Can someone tell me, why they are updating it in Chrome, and why they abandoned it in Firefox?

UPDATE: I've installed Coupert as a better and often updated alternative.
