Those carts are just as big as regular shopping carts. Just a bit taller. It isn't that big of a deal lul. Also for every big shopper cart there isn't 5 or more regular carts filling up the store and blocking lanes. Really it's convenient. What peeves me is the resrockers blocking so much area with their pallets but I know they also restock overnight so it's unavoidable if you wanna get product that just sold out.
