What! Stores in Gloucester has received an emergency delivery of 350 swimming pools.
As the county swelters in the longest heatwave for years paddling pools have been virtually impossible to get hold of with many outlets selling out.
At What! Stores in Eastern Avenue, 600 pools sold out within a few days and over the weekend more than 30 people were queuing outside the store before it opened to grab the last few in stock.
Marketing director Martin Hughes said demand had been unprecedented.
"It's been unbelievable," said Martin.
"I understand we were the last place anywhere around here where you could buy a pool - it's been crazy."
After scouring suppliers 'far and wide' What! Stores has now had 350 paddling and swimming pools delivered today with a further 200 expected on Friday.
The pools range in size from little paddling pools for £6.99 to a big 10ft swimming pool for £62.99.
The firm is also expecting a consignment of stand fans on Friday after selling more than 200 in 24 hours last week.
