if a supermarket had carriages with built in scanners to scan your products would you like that idea?

Q:

A: I think it would be a good idea - It has been used before though, Safeway in UK had them, not sure if they still do though. It's nice to have an idea how much you're spending as you go along. As well as adding, you should be allowed to remove (subtract) items as you may change your mind about buying something.
