Grocery bills rarely balloon because of one big splurge. More often it's a handful of small routines, repeated every week, that add up without anyone noticing. See how many of these sound familiar.

1Walking in without a plan

Heading to the store with only a vague idea of what you need is one of the easiest ways to overspend. Without a list, it's natural to grab whatever looks good, buy duplicates of things you already have, and forget the one ingredient that sends you back for a second trip.

A list doesn't need to be elaborate. Before you shop, glance through the fridge and pantry, sketch out a few meals for the week, and write down only what those meals require plus the staples you're actually low on. Many people keep a running list on their phone or on the fridge so items get added the moment they run out.

Once you're in the store, treat the list as a guide rather than a suggestion. It's fine to swap in a cheaper vegetable or pick up a genuine bargain, but if something isn't on the list and wasn't planned, give it a second thought before it lands in the cart.
