I currently have over 2,000 sports card ebay auctions running.
All have low minimum bids, and most have not yet received any bids. bajmurray's ebay auctions
I combine shipping on multiple won actions, and always ship in either bubble mailers or white card boxes (depending on lot size) and use Delivery Confirmation.
Even though ebay makes me state that I only accept PayPal, I'll also accept money orders and personal checks (especially from TCC members!)
Feel free to either post in this thread or PM me if you have any questions!
