Shopping once a week with a plan beats frequent top-up trips on almost every measure: less money spent, less time in stores, less food wasted. Here’s a routine that takes about ten minutes.
Step 1: Check what you have
Glance through the fridge, freezer and pantry first so you don’t re-buy what you’ve got.
Step 2: Plan a few meals
Choose a handful of meals for the week — see our meal planning system. Note the ingredients you’ll need.
Step 3: Build one organized list
Combine everything into a single list, grouped by category so you shop in one pass.
Step 4: Set a budget
Attach rough prices and set a target for the week — see budgeting for groceries. Cartly brings the list and the budget together, so steps 3 and 4 happen at once and you walk in knowing your total.
Step 5: Shop once, stick to the list
One focused trip, list in hand, and you’re done for the week.
