A glitch on a delivery app saw jammy shoppers bag thousands of pounds worth of alcohol for free - just before Christmas.
The loophole involved using a delivery code on the Gorillas app to get £25 worth of goods.
The only expense shoppers had to fork out for was £1.80 on delivery.
It appears some people were also able to use the code multiple times - although it isn’t clear if they used one account to do this.
One extremely cheeky shopper claims they got £2,000 worth of booze by taking advantage of the glitch eight times.
A source told The Sun : “People absolutely rinsed it. This guy I know had the same delivery man out eight times and he got £2,000 worth of drink.
“Another three or four people I know got £500 to £1,000 worth of alcohol and groceries. The company must have lost thousands of pounds!”
One picture shared with the newspaper showed someone’s bed covered in around 20 bottles of wine, whisky, gin, Sourz Apple, Aperol, amaretto and beer.
Branded alcohol that some customers managed to purchase include festive booze such as Jagermeister, Gordon's gin and Baileys.

The app error apparently lasted 24 hours, according to reports.
Gorillas is a German on-demand grocery delivery company launched it services in London earlier this year.
It boasts of being able to deliver groceries within ten minutes of being ordered by using dark stores, which are distribution centres that cater exclusively for online shoppers.
Gorillas declined to comment when asked by The Sun. The Mirror has also reached out for comment.
Your rights when it comes to price glitches
Sadly, shops usually don't have to honour price glitches – but there are exceptions.
Martyn James, consumer rights expert at Resolver, explained how if the mistake is spotted before you buy the item then the shop doesn’t have to honour it.
"You might want to have ago at haggling, but you’ll have more luck with the head office than the poor person stuck on the till all day," he said.
"So photo the mispriced item and see if you can get some cash back later.
"However, if you’ve bought the item at an incorrect price innocently, then you should not have to pay back the difference if the shop realises the mistake."
When it comes to online, Martyn says it often depends on whether you have bought and paid for the item, and if it has been delivered.
He explained: "Not all online transactions are contracts. So check the T&Cs on the website.
"Where a contact exists the business usually has to honour it if you’ve bought or received the goods though there may be exceptions in the T&Cs.
"That sounds super complicated – but in most cases the retailer’s website will confirm that the order has been accepted. If that’s the case, they should honour the price you paid."
