@Hoss @c tbh before I moved further out into the country I used to go out late at night with a high load backpack and dumpster dive. Winter is an especially good time for it for obvious reasons.
Case the store for the meats and stuff, take not of the expiration dates and plan accordingly.
Little known fact. Little Caesars bakes a shit load of pizzas even without orders to do so. They usually throw them out at the end of every day still warm and boxed. By 11:30pm the last employee usually leaves those stores. Plan accordingly. lol
