Posted as a tip as relevent to those who have/are going, to buy a Flash CarWash System.
Poundstretcher have been out of stock of this for the last couple of months, though all stores should now have recieved stock again.
The prices of these have risen on Ebay, and are selling at over £5 a bottle, due to the shortage of availability on the high street.
Poundstretcher also have plenty of the Car Wash Kits @ £5.99, and water refills @ £1.99
This thread will probably run into a debate on if the Car Wash System is good or not, but i posted this so those, who like me have been after the shampoo for sometime, are aware they can get it again at £1.99 a bottle.
