Its on here as a guide to using the cloths not as a sales ad for the one shown, Mine was £24 for a car pro cloth, halfords charge £12 I think for a mitt type, but what you need to bear in mind is that you can pay between £10 to £30+ for clay bars and they will not last as long by the very nature that the clay keeps the contaminants in the bar itself.
I hear what you're saying for sure.
