Heres what you do. And it may have been mentioned. I sell for a local collectibles shop. Not the point of the story just FYI.
List a ton of stuff for .99. Right now eBay is having a free gallery month.
So list the hell out of anything you can get you hands on. .99 is the best advertisement. In your listing state that your new to eBay and look forward to selling your first couple of items. Some people like being a first customer. When I opened my second account I did this and had feedback stating they were happy to be my first customer.
'Give fair shipping but make sure you cover your expenses. I actually make a few dollars on shipping.
Use good lites and take the best pix you can. Then apologize in your listing for poor pics and your new and don't have a good camera yet. But promise the item is as described.
In your listing promise you will ship next day. Then as soon as the item sells and is paid for ship it. If you can ship it the same day its paid for, do. Then email the customers who paid and tell them it shipped.
What your doing is looking for great feedback. Not just thank you, or got it, or OK.
When I opened my second account for collectibles my FB was 'WOW! got it so fast great seller'. 'Blistering fast shipping incredible!'
'Great! Item as described fast shipping'
One of the pet peeves on eBay is slow shipping. People don't want to wait!
Then, after they leave you FB, leave them really good FB. Like, 'Excellent buyer. Fast payer!!!!!!'
Also, I know sellers have been having problems with eBay restricting their account. Awesome feedback could be the final decision to not restrict an account.
On items that dont sell. I have had so many items not sell the first time and then sell for more than I thought the second time around.
I had a Bo Jackson bb card not get even a watcher one time and then sell for 10$ on the re-list. So unless the item is an obvious crapper, re-list. Sometimes if I am lazy I re-list 50 or so items that didn't sell. I'll sell 5 to 15 of them. And since I list everything for .99 and no pic if there isnt a special. It only cost 10.00 for fifty listings.
If I make 3$ on shipping and sell ten I made 20$ not including what the item actually sells for.
