I have a non folding Wald basket attached to the side of my rear rack by stainless hose clamps. It's a bit banged up, but is a couple decades old. When I was doing more regular shopping by bike, I had a Wald basket on each side. My dad shopped by bike for years, and his preference was for a large front basket. Agreed about laying stuff on top of the baskets after they are full. I've also carried things like building materials that way.
