I am pretty new to selling on Ebay, but as I learn bikes better I find the only way to get a good deal is to sell stuff on Epay. No offense to the forum but I have to list something much below Ebay prices to even get a tiny bit of interest. so for example, I sold a set of shimano tri color downtube shifters for $50, I don't think I would have gotten half of that here. so 50- 18 percent= $42, I am not sure if your 18 percent includes shipping but I charge shipping plus 2 dollars for my time. so my net profit on $50 is $44 or 88 percent. Now if we are splitting hairs lets see what else Ebay gives you. I don't need a store front, ebay takes care of that, Ebay sends out Email reminders to the people watching my item, markets my item, and has a huge multinational market presence, ebay hosts my auction page. once paypal takes over I have a secure way to get the money from the buyer (you know credit cards take a percentage of a sale too right?). not to mention Ebay subsidizes my shipping cost to the tune of $70 cents on a small flat rate box.
