TL; DR 12. How to Do Effective Food Shopping (89 words)
Plan the week’s meals, then write a list from the plan. Buy what you will eat; less ends up in the bin, and you avoid a second trip.
I file my plans and recycle those that work well.
Keep a running needs list; when something runs low, add it straight away.
If you use the same supermarket, write your list in aisle order so you walk the shop once without doubling back.
Do not shop when hungry. Hungry shoppers buy more, and they make poor choices, seeking a quick fix.
Buy the staples in bulk; buy the fresh food often.
First action: Plan next week’s meals, then write the shopping list from the plan in aisle order.
