So yea, 3 for the price of 2 on all chemical car cleaning products, such as wax, polish or shampoo.
Does not include things like sponges or brushes but if that particular item comes bundled with a chemical item then it's ok!
I bought 3 autoglym products:
Autoglym Wheel Clean kit (1L wheel cleaner + 2 brushes) £14.99
Autoglym Polish Kit (Includes super resin polish + Shampoo + Sponge) £17.99
Autoglym Shampoo and conditioner 2.5L £14.99
Total with the discount = £32.98, saving of £14.99!
