We've started collecting used postage stamps in the office.  Please start collecting and ask all your friends and colleagues to do the same.
The stamps should be removed from the bulk of the envelope, just leaving about 5cm around the edges.  We don't want the whole envelope!
We can get more for them if they are sorted into (a) UK stamps (all types) and (b) foreign, which (apparently!) includes Channel Islands &  Isle of Man ....

Don't think we'll make a fortune on this but every little helps.....

To our American colleagues, we'd love all your stamps too please!  See if you can get a sackful by October!
