The folks at Amabuddy.com are on the right track with their site. Say you’re at a store and come across a book or CD you’re interested in buying. It’s on sale, but you would like to know if the price is still better than online stores. Simple. Pickup your cellphone and call Amabuddy, type in the ISBN of the book or CD and listen as Amabuddy gives you the current prices for that product on Amazon! Great concept!
