Yes, exactly. Put lots of time into alerting all these old customers you are leaving feebay and joined ebid by email (PP has emails). Put together a perky little invitation with your store addresses and something about ebid on it to mail. Add pumpkin pictures or something so it does not look like spam. This is direct marketing to a target audience and is VERY effective.
Print some of the invites out as cards, and pass around to friends and strangers when selling on line up. Give to sellers who are disappointed and looking for alternative. This is direct marketing to a target audience and is VERY effective.
