Personally, I find the shoppingcart feature a gimmick. I would have to worry to much about the bike tipping over. The rack version that I have doesn't turn well either so now you have to lift the frontend as well. I like to have both hands available to pick out groceries and what not. Also I don't think the store would appreciate it if I stuff the non-paid stuff with all my junk in the bag or mix it with things I bought at a different store just prior. What works great is folding it up and placing the bike into the shopping cart. It likes to get a little pampered as well.
