I vote with my feet when companies have annoying adverts. I can happily say that webuyanycardotcom will never see a red cent off me, and I switch radio channels every time their advert comes on.
I had SafeStyle Windows cold-calling at my door a while back. I said that yes, actually I do need double glazing, but not from you because of your really annoying advertising. The salesman’s reaction suggested that I was far from the first person to tell him this.
