@Shawnie48 Yes, Get to Work will allow you to add &/or purchase retail stores. They are not grocery stores per-se, but you can sell prepared food and most produce on shelves by ringing them up for individual items, or by adding 'Lice Cold Freezer/s' to the lot and dragging produce (not herbs or spinach) and prepared meals/baked goods into the freezer, and in the store the items in this freezer are automatically for sals... and customers can purchase directly from them (without being checked out)... easy-peasy... my favorite item in the whole pack, and one of my faves in the whole game for that matter! If you don't own one of the stores the game will automatically run it.
You will need Dine Out if you want to add restaurants, and you can own them also. And if you don't own those the game runs them for you.
Country Living is really cool and adds the ability to order your groceries, and you can sell your produce in a 'Farmer's Market' type of way: https://youtu.be/Kgtgookxjtc
Anyway rather than going down a rabbit hole of which packs add which features, those are some initial thoughts on some features that may be of interest, and you can learn much more at that link I shared with details on packs. Have fun! 🙌
