Several stores I never heard of in this thread.
Local grocers are HEB and Randall's, with a Whole Foods not too far away. We USED to have Albertson's, but they closed. (Randall's is now part of the Albertson's/Safeway brand.) I think there's an Aldi somewhere at the other end of town, plus there are HEB's "upscale" Central Market stores, Trader Joe's, H Mart (Asian), Fiesta, and a couple of "organic" stores, most of which are inconveniently far away and seldom worth visiting unless you're going to be nearby anyway for something else.
HEB is preparing to take self-checkout to the next level - locally they're installing a couple of things that look vaguely like airport security scanners - I THINK they want people to use a phone app to scan their stuff as they put it in their cart and then go through the scanners to pay, but I'm not sure how it's supposed to work. I've seen a very few people trying to go through and it appears the system has a few glitches and isn't going to catch on very quickly - looks too much like they're herding people the way ranchers herd cattle.
