I always had a plan that started with splitting the group up and sending teams out for different supplies, which one team would definitely go to Walmart, but not to stay. Just grabbing non-perishable items.

Another team would hit up a sporting goods store, primarily for melee weapons. Depending on the severity and time value in the situation, there may or may not be an attempt to get firearms and ammunition (which are usually in the "lodge" area near the back of the store).

And so on and so forth until there's necessary supplies acquired and the group would mobilize, stopping only when absolutely necessary.
