Households throw away a surprising share of the food they buy, and most of it is avoidable. The waste almost always starts at the shop: unplanned buys, multipacks you can't finish, and ingredients bought for a single recipe that never get used again. The good news is that the same habits that cut waste also cut your bill.
Plan before you shop
The single biggest fix is deciding what you'll eat before you go shopping. When you buy to a plan, you buy what you'll actually use — not a hopeful bag of salad that liquefies by Thursday. Even a rough plan for four or five dinners makes a huge difference.
Shop your list, not the aisles
Bring a list and stick to it. Impulse buys are where both waste and overspending live. A list sorted by aisle also gets you in and out faster, with less time to be tempted by things you didn't plan to buy.
Reuse ingredients across meals
Plan meals that share ingredients, so a bunch of coriander or a tin of beans gets used twice instead of half-used and binned. This is the core idea behind our budget meal plan — reuse what you buy, and waste almost nothing.
Cook from what you have
Before each shop, build a meal or two around what's already in the fridge and freezer. Treat the things nearing their date as the starting point, not an afterthought.
Meal Planner does this automatically: it plans around the ingredients you already own, reuses them across the week, and sums everything into one list — so you buy what the week needs and little else.
