Answer:
The answer is: A) buying food in bulk, if it can be used before spoiling
Explanation:
Usually if you buy any product in bulk you will save money. The problem is that it is hard to use 100 gray t-shirts everyday unless you own FB and don't care about anyone else's opinion.
Usually if you buy food in bulk you are going to spend less than if you buy groceries at a supermarket. That is exactly what retailers do, they buy in bulk and sell the products in small quantities earning a profit.
