We usually Uber off to walmart our first night (easy cause it's all adults so there's that. but we usually get more variety for the same cost/cheaper than delivery).
-Fruit/veggies (specifically those pre cut snack packs)
-Uncrustables
-Bagels or wheat bread with peanut butter or the like to top it with
-Yogurt
-Granola bars
-Wine/beer
We usually get things we'll be having for snacks or breakfast, to help save on those costs, and obviously the alcohol is way cheaper!
