One keen-eyed Farmfoods customer noticed that their local supermarket was selling multi-packs of J2O for less than £2, and was quick to share the news online.
Sharing a photo to the Extreme Couponing and Bargains UK Facebook group, the shopper noted that a range of flavours were available for the low price.
It is the Spritz variety of J2O drinks — which have a sparkling texture to them — that are included in the "bargain" offer.

Taking to Facebook, the shopper wrote: "24 pack of j20, £1.99 in Farmfoods. Also had different flavours."
Before long, the post had attracted almost 700 likes and a staggering 1,400 comments from Farmfoods and J2O fans sharing their thoughts.
One said: "Incredible price!!! I love them".
"That's brilliant," a second commented.
"That’s a bargain," echoed a third.
A fourth posted: "Darn it. Wish I could get to farm foods".
"Bloody lovely that price," a fifth exclaimed.
"Oooo sounds nice that," a sixth agreed.
"We need to go Farmfoods," said a seventh after tagging a friend.
An eighth stated: "Get to Farmfoods.. lol.. bloody bargain!"
"Wow that's good," a ninth simply said.
"I'll have to get some when I go up there," revealed a tenth.
However, not all members of the group were a fan of the apple and watermelon flavour of drink that can be seen in the shopper's photo.
One wrote: "Watermelon apple? Dunno bout that £2 for 24 though amazing".
"Not for me - don’t like watermelon flavour," shared a second.
A third commented: "I’m not a fan! Haha we’ve had it in the big bottle".
