Shell in San Marcos (5403 IH-35 S)

Stopped by because the prices were ~$0.40 cheaper ($2.79 vs $3.19) than other local stations and I was filling not only the 18G tank in my Ford Police Interceptor, but 10 5g gas containers. While I was filling them, a very cute lady pulled in next to me because the same price was still up on the sign, but by the time she put her card in they had raised the price up to $3.19 (she didn’t notice that), and she was not a happy camper when she discovered that because she had driven over from Sam’s Club where gas was $3.13 for Regular, so by using this app and by relying on the price on their sign she ended up paying $0.06/Gal more than she would have if she’d just stayed put.Kinda uncool.They definitely should have changed the price on their sign a bit before they changed the price at the pump so they could avoid the perception of people that they were doing a bait & switch thing. I’m sure they didn’t mean to, but that’s the bad taste they left in that lady’s craw. I was luck that

Friendly courteous staff great choice of food and beverages

This store will be closing on March 5, 2026
