Having a grocery list is probably the most important of these methods. If you stick to your list, then you’re going to have zero unanticipated expenses. I use a to-do list app on my phone, but some apps were made literally for a grocery list.
Shopping the store’s perimeter means avoiding the aisles as much as you can. In other words, you’re going to be buying fresh meat, fresh fruits, fresh vegetables, and fresh dairy.
Name brands honestly are such a scam. You’re paying for a brand, and that’s it. You can’t tell the difference in quality, and if you say you can, you’re lying.
This is a grocery shopping MUST. It’s imperative to know how to calculate unit costs with items. Many stores will have the unit cost on the price tag, but not all will, or maybe the units vary slightly. You must compare them to make sure you’re comparing apples to apples.
The store will discount their fresh items, which is a buying opportunity for you! So stock up on some of those items, even if you don’t need them, and throw them in your freezer.
