Martin Lewis' MSE shares how to get up to £90 off at Sainsbury's, Morrisons and Iceland
The advice comes as the cost of living is soaring with the rate of inflation hitting seven per cent in April - the highest it's been in 30 years.
According to the Daily Record, if you use all the codes provided at different supermarkets, you'll be able to cut the cost of your shopping by £90. And if you're extra savvy with how you shop, you can save even more.
The MSE newsletter explains: "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 per cent 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."
The newbie codes guide covers the larger supermarkets where shoppers have to book a slot in advance. Sainsbury's are currently offering shoppers £15 off their first big shop that comes to £60 using code SPPC22MAY15. Delivery costs around £1 - £7 from next day. The code is available for deliveries by Tuesday, May 31.
Meanwhile, Iceland do offer £5 off your first ever online spend that comes to £45 using the code ICEFIVEOFF.
Delivery is also free for any orders for over £40, meaning you won't have any added costs at the checkout.
Over at Morrisons, you can grab £20 off your first online order through Amazon that comes to £60 using the promo code SPRINGMOR20.
The offer is only available to Amazon Prime members and shoppers can choose their own preferred delivery slot. The code is available until 11.59pm on Tuesday, May 31.
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. The discount code is available until Thursday, June 30.
For anyone that have never grocery shopped online before, supermarkets are offering new customers discount codes to incentivise them to buy online, totalling £90 overall.
Anyone who hasn’t shopped online before can get in on the discount but returning customers might also be offered codes to get money off.
Shoppers have also been advised to 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.'
