Knowing which supermarket offers the cheapest online food shopping is really handy for parents running a busy household on a budget. 

With food prices still high, you might already be shopping at the cheapest supermarket, but if you want your food shop delivered straight to your door, you'll need to pay for the convenience, joining the 43% of Brits who place a delivery order from a supermarket at least once a month, according to online supermarket Britsuperstore. It's a good idea to make sure you link your supermarket loyalty card to your online grocery account to maximise any points and perks you earn.

Here we look at how you can make sure you're getting the cheapest online food shopping, how much the biggest supermarkets charge for delivery, and whether supermarkets charge more for groceries brought online. We'll also compare the pros and cons of online grocery shopping to help you make the right choice for your family. 

Cheapest online food shopping

To get the cheapest online food shopping, you need to be flexible about the day and time you get your shopping delivered. Supermarkets charge more for delivery at peak times so getting your food shop delivered in the early evening or on a Saturday is the most expensive time, but if you get it delivered later in the evening mid-week, you'll likely get the cheapest delivery price possible. 

Richard Price, owner of Britsuperstore, says: "Delivery charges are subject to change week on week, but they do largely remain at stable and consistent rates. It appears that the late-night slots are always offering the cheapest value, and therefore the best value-for-money prices and this is something consumers should be taking into consideration when placing an order."

If you get your food shopping delivered every week, then it's worthwhile considering a delivery pass from your chosen supermarket, where you can pay upfront for deliveries for the month, six months or a year, which can lead to significant cost savings.

How do supermarket delivery costs compare?

If you want to get your food shop delivered straight to your door, you’ll need to factor in delivery fees. These will vary depending on the supermarket and the time and date of your delivery. Midweek slots tend to be cheaper than weekends, for instance.

You can usually pay as you go or opt for a delivery pass which covers you for up to a year and means you can get free delivery any time.

 Do supermarkets charge more for online orders? 

Online grocery orders cost more than shopping in store as delivery costs are added on top. But without the delivery costs, the price you pay for the items in your online food shop will be exactly the same price as those in store on the day of delivery. This is an important point to note as when you check out your online ahead of the delivery day, you're actually checking out with estimated prices, and come delivery day, these could have gone up or down. 

You payment is actually taken on the day of delivery, where exact prices will have been confirmed. If you're on a tight budget, it can be helpful to check your digital receipt that is usually emailed to you as soon as payment has been taken. If anything has gone up in price and you are not happy to pay the extra, you can return it to your delivery driver and get your money back. 

Supermarkets review their prices regularly for a number of reasons. On its website, for example, Sainsbury's states: "There are lots of factors which can affect pricing, from costs of raw materials, to the production and packaging and even transportation."

You should still be able to buy a wide selection of products as you can in store, but during busy periods you might find your favourites have sold out.
