Tips for saving food expenses
1. Buy raw materials as needed
2. Cooking yourself, because if you buy outside it will be more expensive
3. Collect coupons or vouchers
4. Find a food shop that is low

Besides having to choose the needs that must be purchased, you can also look for large discounts and promo prices. In my country discounts or promos are held only when there is a big event and weekend while weekday prices return to normal, therefore you should buy food ingredients for weekly to be more efficient. Whether it's happening in my country or in your country too?
