Martin Lewis: Offers currently available at UK supermarkets

The consumer champion explained details of several different offers currently being advertised by supermarkets.

Here are the current deals:

Free £2.50 box of PG Tips Plus tea

If you go to the PG Tips website, you can get a digital coupon for a free box of 20 PG Tips Plus teabags, up to the value of £2.50, valid at participating Co-op stores only, not online. 

The promotion has been verified by PG Tips, but it's subject to availability as not all stores will have stock. 

All of the offers are subject to availability and people shouldn't make special trips out to just pick up these items

You'll have 10 days to use the coupon from when you sign up.

The coupon's available until Wednesday, Feb 17, or when 7,000 are claimed. Unlike a regular printable coupon, this coupon is digital and can only be used by showing it on your smartphone, which means you'll need to give your mobile number to get it.

'Free' £2 Moma porridge sachets from Sainsbury's

If you shop online at Sainsbury's and enter the code FREEOATSACHETS at the checkout, you can get a free box of Moma porridge sachets, 7x35g (norm £2).

There are 6,000 codes available for shops delivered by Tuesday, Feb 9 but the offer will expire sooner if all the codes are used.

Sainsbury's 'freebie' codes like this one are only valid once per account, though multiple different codes can be used on the same delivery. 

Note: In order to use this code, you'll need to have met the minimum order of £25 for delivery (which costs £9 max for orders under £40, £1-£7 for orders £40+).

'Free' £1.80 Jord oat milk

If you're shopping at Asda, Co-op, or Sainsbury's and pick up a 1L carton of Jord oat milk (find it chilled with other milk alternatives), make sure you keep your receipt and packaging safe as you can claim back the value up to £1.80 when you upload your receipt via the Shopmium app and scan the product barcode.

You'll need to photograph your in store or online receipt and upload it in the app, and you may also need to scan the product barcode.

Note: Check the app before you buy to ensure you've been offered the deal, and don't buy unless it's something you'd use anyway.

'Free' £2 Lindt chocolate for Shopmium cashback app newbies

If you're new to cashback app Shopmium (get it via Google Play or Apple App Store), you can get a 'free' £2ish Lindt Excellence 100g chocolate bar.

Once you've signed up, you'll need to enter the code MSE in the app, which gives you access to the offer – it'll be added to your account automatically.

Within 15 days of entering the MSE code, buy either the 'extra creamy', '70% cocoa dark', or 'dark a touch of sea salt' flavour at any store (including online).

Take a photo of your receipt and upload it in the app, then select 'Request My Cashback'. You'll also need to scan the product barcode when you upload your receipt photo (so keep the packaging). You'll get the price of the choc back, up to £2.40 – when we've looked the choc usually costs about £2.
