New seller here - US Classic stamps
I recently joined hip after several years on that other site. This seems like a simpler place and I hope I can help fill some of your needs and answer your questions. I'm just one person, so I only have a few hundred items, and I do everything myself. I have over 1500 feedback on the other site if you'd like to check: Look for the "RLS Stamps" store to see. I'm a long time collector turned seller. I always provide all relevant details on stamps listed - no hidden faults.
