Fed up with junk mail? sick of all the take away leaflets on the mat when you get home?

Don't throw it away or stick it in the recycling, keep it, sooner or later you will get some junk mail with a pre-pay envelope, fill that envelope with all the junk mail you can, and send it back to them!

A little note along the lines of...

Stop sending my your junk, and I will stop sending you mine!

can sometimes be a nice addition.
