Just go to forums at the top of the page. Scroll down to the section called Stamping Stuff. Near the bottom of that section it will say Buy/Sell/Trade. In that section you can learn to just list your stamps here on Splitcoast.
You are also welcome to PM me if you have any problems.
Good luck with your sales.
You spend 90% of your adult life hoping for a long rest and the last 10% trying to convince the Lord that you're actually not that tired. ~Robert Brault,
