Farnell have minimum orders and the like. Probably $10 minimum order and then something like $15 postage. So not cheap. Order some batteries or something to get to the minimum order.

Stu's generous offer though would be a good way to go. They could just drop in a regular envelope for $1 or so postage even from the US.
