As my first auctions on e-bay draw to a close, I have a few questions. what if my items don't hit my reserve? can I contact the high bidder and try to make the sale somewhere in the middle? how much should i have posted for shipping? I referenced the usps flat rate shippers, but I think ups might be cheaper? Does it cost anything to restart an auction after it's finished without a sale? What is the expected mark-up for new figured? i know it varies, but I don't want to scalp, just make back what I spent plus a little to keep my hobby going. i'm just starting out, trying to learn how it all works. Any tips from seasoned sellers are greatly appreciated.
