I realized that I should have read the eBay rules more carefully when one of my mini-CTU's was removed for being a duplicate listing
So in order to have two similar auctions up at once I decided to add some wheat pennies to the second auction, use a different picture, ask a different price etc. So far it seems to have been OK. What other strategies have you guys used to list as many copper auctions as possible without breaking the rules? Thanks!
