Very small shopping carts?

I'm living half an hour out of town, and would like to come in once a week to grocery shop. Unfortunately none of the supermarkets I've been to has decent sized shopping trolleys.

They don't fit much more than a basket, and nowhere near enough food for a week. Am I the only one with this problem, or am I missing the obvious solution? Last time I filled one basket at three different supermarkets (carrying one in each hand made shopping hard), and I'm currently thinking about making a train of small trolleys. I realize both these ideas are stupid but I'm really struggling to think what would a normal person do
