Well, popped into store today, great deals to be had. 3 for 2 on all cleaning products that includes power washers, car hoovers and various cleaning products. I picked up two bottles of Auto Glym 'Bodywork Shampoo Conditioner' 2.5 litre bottle and a £12 shammy, £27 the lot. Bare in mind the shampoos are £15 on their own, this is a very good deal.
PS The shampoo is the best i've used. States 125 washes from the bottle, so will last a few years for most people.
Sorry I meant £30 the lot.
