Of course when there are options, more often than not personal preference comes into play and best usually becomes subjective. I would imagine if you were wanting to use it for shopping purposes, that one of the other scanners may be a better idea. https://play.google.com/store/apps/details?id=com.biggu.shopsavvy <-- perhaps shop savvy for example.
Thanks cupfulloflol. I just downloaded the shopsavvy scanner app for my Razr w/ice cream and tried it out on a few things around me. I got excellent on-line pricing options. The scanner worked well and one touch on the price list connected me to the vendor's site where I could make sure it's the same item. I see this as a very nice way to check out the value of a purchase.
