While it's became fairly common for people to flog unwanted gifts on eBay, some eager beavers were setting up auctions mere hours after Santa had popped down the chimney - with some of them not even bothering to unwrap the presents before putting them up for sale.
Yup, in what appears to be an unprecedented move in an unprecedented year, there are people selling off unwanted presents before they even know what's inside 'em.
That's really not very Christmassy, guys.
One such seller hints at a relationship breakdown, writing: "It's a long story, the gifts are from someone I no longer want to be in contact with!
"Let's just say crazy person!
"We now don't talk but the gifts were given before the fall out!
"Hope the gifts will be appreciated by someone else as I don't want them."
And despite not giving even the slightest clue as to what's inside, it's picked up almost 40 bids, which currently stand at £63.
A bargain if it's some fancy aftershave, less so if it's a box of that horrible shortbread that's always knocking about at this time of year - or worse, an empty box.
A newly single person trying to flog an unwanted, unopened gift - with bids currently at £20 - described the item as: "Christmas gift has been given to me by my ex-boyfriend."
While another listing has three wrapped-up items for £19.
Again, it's fairly impossible to know if that's a good deal or not given that the seller could be sending you pretty much anything.
I don't need to tell you savvy lot that buying something when you don't know what it is could be a recipe for disaster.
The online auction site will refund buyers if what they buy isn't as described, but if you're buying something that is only described as an unwanted, unopened present then you're going to struggle to make a claim on whatever is inside.
Earlier this month, a bloke in Utah learned the perils of online shopping when he bought a PlayStation 5 off eBay for $878 (£656) only to be sent a concrete block in the post.
According to Fox News 13, the package came in a PS5 box, but when the man opened it he found himself the proud owner of a brand-new block.
The poor fella even contacted police over the scam, who reassured him that thanks to eBay's protections he should get his money back.
Stay safe out there, guys.
