The 1000g packs are filled to the brim with the more-ish piggies, and adorably, each jar features Percy's smiling face.
Ideal for storing your Percy Pigs, the glass jars were spotted by Instagram account @kevssnackreviews, who also revealed the brand has released a Percy Pig piggy bank, too.
"New Percy Pig Sweetie Jars and Piggy Banks at M&S!" They wrote.
While the glass jars are priced at £15, the bright pink piggy banks will set you back by £10. We've got a feeling these are going to make some very tasty stocking fillers come Christmas...
And fans are already going wild over the Percy Pig offering, with one person writing: "Christmas sorted" while others tagged their family and friends as a hint.
"My birthday is coming up," said one.
By the looks of things, both the jar and piggy bank are already available in stores. And with Ocado now offering M&S food for delivery, it might not be too long before you can get them delivered to your door.
In a joint venture with Ocado, M&S now delivers groceries from its food hall straight to your home, just like other supermarkets do.
M&S CEO, Steve Rowe, said of the venture: "Our partnership with Ocado will create shared value for our customers, colleagues, supplier partners and shareholders, operating with a common sense of purpose and values.
"This is a transformational step forward in shaping the future of M&S and in becoming a truly digital first retailer with at least a third of the business online."
We have to get our trotters on these Percy Pig jars ASAP. Trip to M&S, anyone?
