I like how you can compare different items in your price range to see which one performs best and give it an estimate of cost savings or loss if purchased over other products at their same price point. It's not very user friendly (it took me about 5 minutes just trying out some things), but they have been working hard on improving this feature so hopefully, soon we'll be able to use the tool more efficiently! You should definitely try using comparative shopping before purchasing any item online. We've saved money by comparison shopping with comparable as compared to paying full retail value when buying certain furniture pieces from our home office space.
