Shopping apps

AP: If you are out shopping you might to have the RedLaser app on your phone. One that I've used the most is ShopSavvy. Both are free, I think.

These apps and others let you scan in a barcode and compare prices. I like ShopSavvy because it will read the barcode quickly. Some apps are slow.

For example scan the barcode on a book, and compare Barnes and Noble, Amazon, etc.
