Have you seen the PriceBlink extension for Chrome, Firefox and Safari? I really hate to shop, even online, but when there is so much price competition online I feel obliged to spend time searching ad nauseum to at least feel like I’m getting the best deal I can find.
When you start shopping and hit an e-commerce site, PriceBlink comes up as a message bar with a drop-down menu of prices for the item you’re looking at, from retailers all over the Internet. If I was doing some serious price comparison I can see this saving me serious time, and money. In addition to price comparisons, there are reviews of products and coupons from retailers.
