Thanks for the TJ's recommendations, everyone. I got the Beans Go Green, and some frozen Indian meals, and some frozen rice medley. For a treat I got apple cereal bars, which are labelled "this apple walks into a bar...."
I picked up a gift card for a cousin who is having a birthday next week. The cashier had trouble loading my requested $25 on to the card, and we thought he got it figured out -- but no, a) the value on the card is the default $10, and b) I wasn't charged for it at all, it's not listed on the receipt. I'm thinking I'll go back Sunday or Monday and get that fixed, and pick up some chips and perhaps some of the other items recommended.
The store is smaller than I expected, only six aisles wide and about 100 feet long. The parking lot is correspondingly small, with perhaps 50 spaces. I parked farther away, and as I walked in passed by a loud standoff between one woman who was standing in an empty parking spot "saving" it for someone, and another woman in a large SUV who had nosed in until her bumper was within a couple feet of the first woman, trying to get her to move. I missed the resolution, they were gone by the time I came out, but there was a police car nearby that hadn't been there before....
