buy 1g rounds from me. I've ordered customized post stamps and you'll get the mail with the (hopefully) first bitcoin on a post stamp (ever ; ))
here's the preview, what is in the highlighted area will appear on the post stamp:
I'll try not to push the prices down and charge .30 btc for postal service / delivery
and somewhere between .41 to .50 per 1g silver bitcoin. more or less the price starts at .50 per type 1 piece, .49 for type 2.
each additional type 2 coin is .02 btc 'cheaper' than the previous, valid for 2-5 coins. so 2 would cost .49+.47, 3 would cost .49+.47+.45 etc.
type 1 only 1 per order.
edit: the shipping fee is usually .20 btc but since the bitcoin stamps cost extra, i pass the price difference of the stamp to the buyer
shipping with a normal stamp is still a valid option i just don't see the logic of ordering a bitcoin and not choosing to have it on the stamp as well.
