Probably the best price comparison I’ve seen. I like the way it’s only visible when it’s found a bargain on the product you’re browsing. You don’t even know it’s there until it finds a better price. The price comparisons are very good: no bad links or out-of-date prices. It seems to compare all the ‘big’ retailers like Amazon, Newegg and BestBuy, although it wouldn’t hurt for it to do more of the smaller ones too. Pros: Accurate. Fast. No pop-ups Cons: Some of the smaller stores aren’t supported.
