I use a walker. When I go to Aldi, 1 put items in nylon bags which I hang from my walker handles. At checkout I put the bag on top of the items and ask the operator to replace items in the same bag as they check them. They always oblige and no one waiting behind me has ever objected.

When I did markets,someone gave me an old metal coin holder, used by bus conductors. it had springs inside each section, pushing the coins up. I still have it.
