M&S shoppers are warning others they plan to stock up on the retailer's latest release after it was hailed as the "dream" product.
The retailer took to its Instagram feed last month to share the news it is now selling 'Marmite Cheesy Crumpets' which are available in packs of 10 for £7.
Its Instagram post gained thousands of likes and plenty of comments including a warning from one customer of their plans to stock up.
M&S' post said: "We Mar-mite have gone and done it again, with our NEW EPIC Cheesy Marmite Crumpets! These bad boys are in store now and ready to WOW! 10 per pack and 3 for 4 in our party food deal - crumpets ... but NEXT LEVEL!"
The user said: "I'm going to be buying at least five packs of these"
And another said: "Omg. I can't wait to have these."
A third added: "OMG I NEED!!!"
And, a fourth said: ""Dream canape"
M&S' new food products have been causing a huge reaction this year. Last week it left its customers speechless after releasing its mince pie cookies.
One user said: "They are delicious! If you enjoy mince pies these are even better"
Another said: "These are so delicious!! Please make them all year round, M&S!"
