I used to travel a lot for work. The biggest takeaway, depending on what state you're coming from, is there is no alcohol whatsoever sold in gas stations. Most every other state I've been to sells beer in gas stations, then has another store where you can buy everything else like wine and liquor. Here, a package store is everything under the sun. Beer, wine, and liquor. Smaller shops will carry at least those 3. Bigger places may also allow you to order kegs and carry mixers and bar tools.
