Not sure how to add this option in!!??? I am interested unless it costs me because I'm not wanting allot for these. Just my trying to get enough to be able to buy-get more stamps to get closer to completing my US collection. Tell me how, please and I'll work on.
I think you have to do that when you originally post your auction. I have looked and can't find the option. Next time I post one, I will look and keep trying to learn more.
