Mine, in $ order:
King Soopers (AKA Kroger, City Market). Their handicapped carts are reasonably plentiful and they have 95% of what I need. I buy my gasoline there, too. I took a picture of their overhead store guide signs so I could plan out my route in there at home, then just zoom around the store in the cart terrorizing other patrons. Disappointed that since they're front-wheel drive, you can't do wheelies. Rats.
Wal-Mart. Specialty items like a kitchen or bathroom scale, replacement Braun Shaver heads, bedroom linens... usually one-off items. In other words, oddball "Department Store" stuff. Good handicapped carts, but sparse. That limits my browsing there if I can't find a 'lectric cart. Their stores always seem to be > 2 acres. Feh.
Harbor Freight. I usually just go in there to pick up a hardware item with one of their coupons, but rarely get out of there without spending >$60 on impulse "gotta have it" buying. I really have to learn to just go in, get what I want, and get the hell out. No electric carts at all, but the strong temptation to browse while leaning on a regular cart is too overwhelming. Mebbe I ought to tell them to quit sending me their coupon flyers. Fliers?
