And with inflation spiking at 1%, our overall costs of living could start to climb a little too.
So it's more important than ever to keep that supermarket bill in check, and we've three key habits you can change to eat well for less.
Switch brands and change supermarket
Though you might have bought the same brand of tea or same make of biscuits all your life, you'd be surprised just how many variations of everyday groceries are made in the same factory with very similar ingredients.
It's down to individual tastes, but if you're willing to try a supermarket own brand product instead of your usual brand it's likely you'll save a decent amount every time you shop.
You can also often save by getting your shopping at a different supermarket. Discount chains often sell equivalent goods for less than the major stores, though don't drive too far out of the way to make these savings if it's going to cost you more in time and petrol.
Plan your meals and make a list
So much money is wasted on wasted food. We throw away £600 worth of food every year, from cooking too much or simply forgetting to use ingredients before they go off.
The simple answer to this is to plan your meals. Check through your fridge, freezer and cupboards to find out what needs using, and then shop for the extras you need.
A shopping list won't just remind you what you need, it'll help focus you as you push your trolley around the aisles. Skip the sections you don't have on your list.
Watch out for deals and compare prices
Some special offers can be great money savers – but the supermarkets don't reduce certain foods because they're nice. They want you to buy things you wouldn't normally get, and therefore spend more money as a result.
So when you're looking at a deal, first think about if you need it and if you can use it.
Don't take the deal at face value – it might not be the best price for what you are buying. Sometimes multipacks are more expensive than single items, bigger "value" packs pricier per unit than smaller ones, and loose items cheaper than packs.
The key here is to compare the price per unit, which should be on the label.
