The new edition of Martin Lewis' Money Saving Expert newsletter has revealed a simple way for people to get up to £55 off the cost of their shopping.
One of the financial experts who works for the website explained that shoppers who order online from Sainsbury's, Morrisons, and Iceland can take advantage of the savings.
These supermarkets all have 'newbie' discount codes for first-time customers to save money on their order.

Expert Georgia-May Collings stated: "Online grocery delivery has gone into overdrive and delivery services (including the traditional supermarkets) are all trying to sign you up with tasty new-customer offers such as 40% off or £5-£20 off – though which you can get depends on where you live.
Use as many as you can, and you'll make BIG savings."
Sainsbury's are currently giving customers £15 off their first big shop totalling £60 or more with the code SPPC22MAY15 .
Delivery costs vary between £1 and £7, and availability will depend on how soon you book.
Iceland meanwhile are offering customers £5 off their first ever online spend that totals £45 with the code ICEFIVEOFF.
Unlike Sainsbury's, delivery is free for orders totalling £40 or more, so there will not be any additional costs.
Morrisons are also giving customers £20 off their first online order through Amazon that comes to £60 with the code SPRINGMOR20.
The offer is available exclusively to Amazon Prime members, and is only available until the end of the month.
The Co-op also offers Amazon Prime members £15 off their first £50 online shop with the code HELLOCOOP15.
Shoppers are able to choose their own preferred delivery slot, and the code is available until June 30.
Georgia-May has also further advised shoppers to check with their chosen supermarket for any multi-buy deals, further offers and free items that you can add to your order to 'max the discount code.'
