Here are tips on how to spend less on food:
Avoid impulse buys: Plan so that you need to visit the supermarket just once a week. Make a list for your weekly menu. That way, once you get to the store, you will be able to shop quickly and avoid picking up things you don't need.
Get a loyalty card: Sales in most supermarkets are tied to loyalty cards. Seek out the items on your list that are on sale.
