Shoppers have been seen queueing for the viral Prime energy drink outside Sainsbury's for the first time.
Prime, which was developed by Youtubers Logan Paul and KSI, have exploded in popularity among teenagers.
We've previously reported how parents were spending upwards of £1,000 for drinks for their children and fans were driving hundreds of miles to get their hands on Prime.
It was already on the shelves of Aldi and Asda, and today was the first time Sainsbury's was going to stock it.
Queues were seen at stores in Maidstone, Birmingham and Torquay, and when the door opened, some shoppers ran to the shelves.
However, the product flew off the shelves as many said they were met with empty 'point of sale' cardboard boxes and signs saying the shops were still waiting for stock.
Some of the parents had been waiting in line long before the stores opened.
Claire Smith, a 52-year-old mum from Solihull, said: "I'd taken my children, aged 12 and 10, into Marshall Lake Sainsbury's.
"They'd been nagging me for it for a week.
"They got me out of bed, all excited to buy it with their own pocket money.
"We dashed into the supermarket, running across the car park to be the first ones in.
"Once they realised there was no Prime in stock, they were really disappointed.
"A sales assistant told us to come back on Friday, but they had it in their heads that they were going to get it today."
The supermarket is set to stock flavours of lemon lime, blue raspberry, tropical punch, ice pop and limited edition orange and mango.
The millionaire YouTubers have reportedly already made £8.3 million from the energy drink worldwide.
It comes as a doctor previously issued a warning over the energy drink.
Dr Deborah Lee, from Dr Fox Online Pharmacy, told The Mirror: "I would not recommend children drink Prime energy drinks or other energy drinks for children of any age.
"Children don't need energy drinks anyway – they have plenty of energy! If your child is lacking in energy take them to see their GP, do not give them an energy drink.
"It encourages them to want sweet drinks, when plain water is the answer and helps them develop a sweet tooth which is not good for the future in terms of a healthy diet and controlling their weight."
A Sainsbury's spokesperson told the Mirror: "We know our customers actively seek the latest in product innovation. We are excited to be launching the following Prime Hydration products in store from Tuesday 21 February."
