YES I love this thing.. Mom ( Babs) and I have used this a ton out shopping..My Husband has even used it for Man Stuff... Like at Home depo for hardwear.
It is called ShopSavvy I believe it was a free app but i got it SO long ago i dont really recall. It is easy to use..
Easy to use.. My Kids love doing it for me.. Keeps them busy in the store. All you do is scan the Barcode on something and it pulls up prices for stores and online stores also like Amazon or Walmart online. Not everything is in there but you can also add things by taken a picture and adding the Info in about where you saw it and how much it was. VERY helpful seeing as Prices are changing all the time. ALSO give you a good idea about how much you have saved shopping at discount stores. If you have a smart phone this is a MUST have for bargin Shopping in my book.. BEAN
