A JOKE solution is quickly get your money and spend everything into food and eat this food you brought.
Imagine a bag full of popcorn, this bag full of popcorn has a price, now imagine magical bag that has popcorn inside it, and as you eat this popcorn new popcorn start to magically appear inside this bag. This second bag have will be more expensive.
This means that the price of a non-magical bag full of popcorn already take into the fact that this item is a consumable.
By spending all your money into food and quickly eating it, you make sure you dont lose value by your money losing value, because you throwed this money at someone else lap, and the thing you brought dont lose value because its a consumable and the price of the thing is already influenced by it.
