How to plan your weekly shop

A ShopLister guide.

A weekly shop without a plan tends to go one of two ways: a trolley full of things that seemed like a good idea, or a second trip on Wednesday for everything that was forgotten. Usually both.

Planning it takes about twenty minutes once you have a routine, and it pays for itself in fewer trips, less food thrown away and a smaller bill. Here is a routine that works for most households.

1. Look at what you already have

Start with the fridge, then the freezer, then the cupboards. Two questions for each:

It saves buying a third jar of something you already have two of at the back of the cupboard.

2. Plan the meals

Count the meals you actually need. Check who is home which nights, and leave out evenings you are out or know will be a takeaway.

Don't forget breakfasts, lunches and snacks. They are easy to leave off and are usually what sends you back to the shop midweek.

3. Write the list from the meals

Go through each meal and write down every ingredient you do not already have. Note quantities as you go: "chicken thighs, 2 packs" saves standing in the aisle trying to remember how many the recipe needed.

4. Add the usuals

Most of a weekly shop is not planned meals at all. It is the same things every week: milk, bread, fruit, cereal, yoghurts. Then there are the things bought every few weeks, like toilet roll, washing powder and coffee, which are the ones most often forgotten.

Keep a standing list of your usuals and run down it every week, adding only what you need this time.

5. Put the list in shop order

Before you go, sort the list into the order you walk round the shop, so you can go up and down each aisle once instead of doubling back. Our guide to writing a shopping list in aisle order shows how.

6. Shop to the list

Make it a habit

Pick the same time each week to plan, such as Thursday evening for a Saturday shop. Keep the list somewhere everyone in the house can add to it, so things are added the moment they run out, not remembered at the shop. After a few weeks most of the list will write itself.

Planning with ShopLister

ShopLister helps with the parts that repeat every week. All the Usuals shows what you buy regularly, with the things you are likely to be running low on marked, worked out from your own shopping, so step 4 takes a minute. Everything you add goes into shop order by itself, so step 5 is already done. And it all works with no signal in the shop.
