> Target is getting awfully close to this. With their Cartwheel app you're meant to scan all your items as you shop (so it auto-applies coupons and discounts); but they haven't taken it to the next logical step and allowed you to provide your Cartwheel output at the checkout for checking out. Tesco in the UK is already doing that. You just finish your shopping by scanning an "end of shopping" barcode, you pay and then you go with your trolley. You sometimes need someone to remove the security tags or check that you're 18+ for alcohol but that's it. However, home delivery is even better in my opinion, it's very common in the UK nowadays. You see those vans everywhere, from nearly all big supermarkets.
