Assuming you're in the US, it's no big deal to stick a couple of stamps in the mail--no trade necessary (my want list tends to the pricey side, as I typically just trade extra sheets for stuff I'd otherwise never run across). Send me your address in a "conversation" and I'll send them out.
Mr. Alvin...I received your letter today and I really appreciate the stamps! Thanks for the extras you included as I needed some of the special delivery stamps. Thanks man!!
Easy stuff. Glad they arrived in a timely manner and that some of the extras proved to be more than trading stock.
