To get a better capture also make sure your camera is parallel to the barcode. It seems to work a lot beter this way. It feels more natural have the camera angled a bit but try to force your self to keep the camera perfectly parallel to the box or whatever the barcode is on when you capture the image.
This app is great. Thanks to all

Maybe try to keep a tally of which sites have the best barcode database or which sites people are having the most success with. So far I'm using fastpricecheck but I've only done a small sampling so I don't have much to compare it with yet.
