Evening All,
Just found this deal....
On eBay Eurocar parts shop is selling a 5L concentrate screen wash for £3.54 - not bad, but if you change the quantity to 2 they give you a third off.
Total price £6 for 10L concentrate FREE delivery - even better
Only works for 2 at a time though so I just placed 2 separate orders of 2.
Enjoy
