I had a young lad call to the door trying to sell me a voucher, which at face value, looked like a tempting offer, but I declined. He tried to tell me that he was working for AP, but he knew what I was asking, so I didn't believe a word he said after that. The company distributing the vouchers at a cost of €99 for over €700 worth of servicing and stuff is called C3 Marketing. I found the exact deal online if anyone is interested. The catch would seem to be that you buy the materials separately and you could be charged through the nose for them.
