Be cautious about offers and discounts.

Buy food that is cheaper because they approach their use-by date, only when you are sure to consume them!

Watch out for advertisements where you’re offered to pay less if you buy more (such as 3 for 2 or + 20% free) – only accept these offers if you really need the larger quantity or can freeze it for a later. Otherwise, you do not only waste food but also your money.
