Thats right Natalie, they sell them...usually its in the form of "KILOWARE"... allegedly unsorted,( they are sold by weight ) you might just find a stamp with some imperfection, or its a cheap way of filling albums for the junior collector. There is no such thing as "scrap... unwanted, these days 99.9% of EVERYTHING can be made use of.... I am a stamp collector, and a Radio Ham... all my stamps go to the local Post Office where there is a box for unwanted stamps to help the poor of Malawi...Wonder how much gets to the poor...!!
