Hi, K.. I live in the Corinth area. We have Atmos and are satisfied. We use City of Denton for other utilities, and they have the best price. Go with the Verizon bundle for phone/internet/FIOS-- it is awesome!
As for shopping, it depends which neighborhood you are in. There's an Albertson's & Super Wal-Mart off of Swisher, but we love the Super Target and Kroger in Denton-- loop 288. They are building another Kroger near the Oakmont area and near Nelson Elementary school that will be convenient from the S. Denton/Corinth area.
Feel free to email with any other questions or share which neighborhood-- then I could give you more specific suggestions.
