admit it, you shop online. Yeah, you go to several different sites to look for the best prices but you stop after a couple because you just want to order the darn book. Well, what if your browser could tell you, automatically, if that item you’re looking at could be purchased for less at another online store?
Invisible Hand, an add-on for Firefox, will “shows a discreet notification when the product you’re browsing can be bought for a lower price elsewhere. It gives you a link directly to the product page at the competing retailer.” Invisible Hand works with more than 50 retailers in US and UK, most importantly for us librarians, Amazon.com and Amazon.co.uk.
