I would like some help on using in store carts. We regularly visit Target and I use a cat while mom, who should also be using one, uses a bit buggy. Often I have had to get one or two carts because they die on me. Is there any advice to help? Should I turn it off while looking at items? Or keep it on? They have older bigger cars that I have actually moved moved displays with. These are not as easy to maneuver but seem to last longer. The other newer carts are way faster, can turn around in most isles but run out of power very quickly. Any advise? I have to use a cane when I leave the house or at home even if neededIn.I have a rollator for when I am going to have to wait line or be at our bookstore for awhile. Also, I met a woman who was in a small scorer she said she got off amazon. It was a two word name that was something like future and mechanical. I fear I may be needing my own. I'd like to see if there are any small, portable cart that I can tool around in. But how could that work in a store or just to even hold my bag (s). As you can tell I need a lot of help in this transition. All and any advice is definitely welcomed.
