Hmmm. There are times this would be very handy - especially in bad weather.
Shopping is a chore, that's for SURE. Make your list, remember to take your list, put items in the cart, go back for items you missed somehow, walk clear around the huge store (good for exercise anyway), then put your items on the conveyor belt, then take them OFF the conveyor belt as you bag them and put them back in the cart, then wheel them out to your car, then put bags in your car, then put the cart away, then drive home and take the bags OUT of your car, take the items out of the bags and then put them away! Whew! Add bad weather and you feel like you've run a marathon! LOL
But NOT seeing new things or getting ideas for things by seeing products you've overlooked before?!
I doubt our stores do this for US because we are 1/2 hour out. ?? But online? It might be worth a go at times! And yes, it would definitely help stay on budget!!!
