Groceries in the Rain

I am looking for shopping carts on Froogle. I found one that will go over curbs. Part of me thinks I will look like a homeless person pulling one of these, but the other part says I am just being more European. I just hate getting in my car just to get groceries. Seems like a waste. Opinions anyone? I am thinking of getting this lovely model (hot pink was sold out)!

This quest began because because, while shopping, I forgot that I was on foot, and loaded up my cart. When I got in line I realized I'd have to pack up the bag myself as the baggers always put about three items per bag. With the exception of a loaf of bread, I got it all in, but boy my back sure protested as I was walking home with it. It was raining pretty good and I had to take three breaks, huffing and puffing, before arriving at my front door.
