As OP sets it up it makes no sense. Not to mention that they already themselves point out the obvious answer, we have done so for thousands of years. Almost any type of food we ever have eaten has been consumed raw, or preserved without fire and fridges somewhere, somehow. But since the store can do the fire thing that means the amount of foodstuffs multiplies massively.
Before refridgeration they pack oysters in ice and send it long ways inland with trains e.g.
The OP mentioned mostly stuff that wasn't particularly perishable, and leaned cheap. Peanut butter can be stored room temperature for a good long while, cheaper breads tend to last a good long while as well (preservatives are your friend here), cashews can be a bit pricier but will also last approximately forever, etc. That's less stone age foraging and more dense calorie sources with a decent amount of protein that still run cheaper than jerky.
