I’ve only gotten the bar code scanner to work on a sandwich. Doesn’t work on candy or chips. Search function doesn’t work. I always get a ‘not found’ result. I couldn’t search Reese’s I had to go to the lookup list. Look up list does not reflect items available. Don’t search for parfait unless you physically see parfait available. Sandwiches in the look up list do not match actual item (as in the picture) the turkey and cheese croissant on the photo showed tomato with actual sandwich not having tomato… if you need to add funds before paying, GrabScanGo freezes. I have to completely close GrabScanGo , go back to my cart and then checkout. So add funds before you see what to buy. I love the convenience, but GrabScanGo needs work.
