Hi Mike,
It looks to me that this seller just started to sell last month and has put all his items in his stores, etc. He last visited a few days ago. Is doing everything right but does not have any sales yet (i.e. no feedback). Given that he sells custom auto parts, speciality items fewer people use, that is not unusual. The sales will come, he has done all the hard work already. He did not ask for help yet.
Marketing depends on what you sell, where you sell it, how you present the items and more. Those who sell a variety of items, at a variety of prices do better on ebid than those who sell only one thing at a set price.
We ask new sellers to read old forums for selling/marketing tips, and if those do not generate sales, come back to the forums and ask for help. Don't wait more than a few weeks as it often just takes a tweek or two to get sales coming. We help anyone who asks.
I have found that buyers are different on ebid, that is the biggest difference. They do not spend lots of time on line, do not fool around in bidding wars. They buy outright or they buy for that first bid price (so price accordingly). If two buyers go after one of my items, one always drops out and bids on a similiar one. Very unusual buyer behavior, but that is the way they bid here. So do not start auctions low (you will get no bids), but at a price at you are comfortable selling item for.
Economy has great deal to do with it too. Don't sell only high priced items, sell some that are below $20, those are more popular now. And of course, don't have high shipping prices. Spell out the shipping terms and prices in the listing. Buyer will NOT bother to contact you for infor.
Welcome to ebid. If you have any questions or problems, just ask, someone is always here to help you.
