Flash Car Wash Filters are available from Pound Stretchers (or their new name!) for 99 pence each, buy one get one free! - fill your boots whilst stocks last!

Every one I have gone to has loads of filters but no shampoo. Still the filters are great for reducing watermarks eitherway you look at it

Poundstretchers and Instore are the same company and sell the same things pretty much.

I have been wondering if perhaps a "bargain" thread or forum section may be useful. I know those sort of things in forums tend to attract spam, but I'm sure we can all point out the great deals around, and help each other save money while looking after cars

Some I have seen around that seem noteworthy include Holts rust terminator 500ml in poundland. Also I got a 1 litre bottle of AutoGlym Bodywork shampoo and conditioner £3.99 from a place called fast parts (only store near Newport). It was 100% extra free so this 100% free offer may be available elsewhere, but that's the only place I have seen it. Also picked up 1 litre AutoGlym Super Resin Polish (yes 1 litre, supposedly 100% extra free) for £7.99 from same place (325ml = £7.99 in Tesco).

Another place that might be worth a look if your passing is Savers. They are clearing their stocks of them for 49p a piece. I know they are starting to sell out but might be worth a punt if you can't get any from Poundstretcher
