Buy.com has been a huge "e-tailer" since 1997, and now they have brought their legendary site to Android! The app brings alot of cool ways to search for what you are need as well. You can type in a search, search by scanning a barcode, or even by speech-to-text! You can check on your orders by signing into your account and also see your previous order history. It's detailed enough that you would never have to actually visit their site again! The only cons I've seen while trying it out is that it currently doesn't support landscape mode and force closes on my XOOM. These can both be easily fixed by a software update, so its no reason to panic. You can get their free app in the Android Market by clicking here.
