Never buy things “Just in case if...”

Never buy things “Just in case if…”

Use shops as storage places. Never buy things if you don’t need them right away or don’t “really” 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.
