It does save money on occasion, but the constant pop-ups of useless info are really annoying - and there's no option to disable them without disabling the entire extension. Useless info being things like: 'you found the best deal!' or 'doesn't work for this page' or whatever. The ONLY time I want a pop-up is if there's opportunity for savings in excess of some threshold value of the item cost; say 5% or $5 - could be user variable in the settings! It'd also be great to be able to blacklist some vendors, like ebay. That said, I'm surprised there are so few users of this add-on. I wonder if there's a better one that I'm not aware of...

I've used this extension for years and it's saved me quite a bit of money. Unfortunately, I've had to uninstall it as it messes up the HTML code of several websites with sticky top menus.

Most of the time the results show the same one I've already picked out or something else entirely (ad?) although I only really look at it when I'm comparing it to what I'm actively purchasing or on pages that have nothing to do with a purchase. Otherwise, the main reason for three stars is everything I look up gets sent to Google search. I'll use this when this becomes more relevant and repaired.
