Many stores have apps and curbside pickup scheduling. Just saying.. otherwise sounds like you're doing the right thing. When I drove to my curbside pickup and crossed the WalMart parking lot, 99% of people were just carefree walking and brushing alongside each other, idling at the entrance, not pushing through. No masks. Not a good sign. I would even hesitate to enter or exit until you can pass through without being in a crowd, obviously. Goooood luck!
