Low carb specialty items that I would recommend getting:

DaVinci Sugar Free Flavored Syrups -- My favorite is Toasted Marshmallow
Keto Oatmeal -- my favorite breakfast. 12g carbs - 9 fiber == 3 net carbs
LaTortilla Low Carb Tortillas
Misc. Atkins Products (my favorites are Ketch-a-tomato and Morning Start bars)
Low Carb Bagels

Most low carb stores have TONS of candy -- I recommend avoiding them as they tend to be loaded with sugar alcohols. Check the labels.
