Never buy things β€œJust in case if…”

Use shops as storage places. Never buy things if you don’t need them right away or don’t β€œreally” need them…
You will still be able to buy them later on, when you will really need them.

Grocery stores and e-commerce shops (e.g. Amazon) are storage places. Use them as if.
Buy things there only when you really, really need them.
