Rated 1 out of 5 stars
A great idea, but it has been a waste of time. There has been only one occasion when the add-on has been useful for me. Otherwise, it has only been a distraction. It almost invariably does not compare like products, or it compares prices between vendors with very different prices for shipping.This review is for a previous version of the add-on (126.96.36.199-signed).
