There's a new product in the shop: 'No Cold Callers' stickers. I'm hoping Stop Junk Mail will increasingly cover more kinds of unsolicited marketing than 'just' junk mail. These stickers are, I hope, just the start.

The design is simple-but-effective (as always!). The stickers are small enough to be placed just above or below a doorbell – which is of course the best place to put a doorbell sticker. And, because they're small they're cheap; I'm hoping to sell them for just 60p each. Buy now before I put the price up!
