When T-Mobile’s G1 phone was unveiled earlier this year one of the things that caught many people’s eyes was the barcode reader app available for it. - Martin Bryant from Bookmarklet

i've used shopsavvy a lot on my G1. very nice - @baratunde

I'm curious to know how population density ( and therefore merchant density ) affects how well this app works. Are there any small/smaller town/city users on G1 that find it effective? - Jamie Dool

I wonder if many folks act on this price comparison info. Post makes a great point about service... Price and selection are big -- but only two value points. Sometimes, being able to get it now is more important. - Eric Johnson
