A great companion to the Amazon app
I shop with Amazon on my phone constantly, and this app makes it easy to make sure Im getting the lowest price before I buy. The barcode scan feature is also pretty handy for comparing store prices to whats on sale at Amazon, and elsewhere. (The Amazon app also scans barcodes, but they only tell you the price for one place: Amazon, of course.)
