The old adage “Don’t go to the grocery store hungry” rings true. When you go to the grocery store or Costco, go on a full stomach and bring a list (divided by type: produce, grains, dairy, cleaning supplies, etc.).
You’ll save money buying only the things on your list. You’ll save time avoiding aisles that don’t contain any items on your list.
In the good old days, we kept lists on the fridge and added things when we ran out. Better yet now, keep a running list on your phone (which you always have with you) so you can shop smart at the store.
