I've graduated from eBay noob to eBay novice with about 30 sales and $1000 net over the past year. :) I've got the first gold star (ten feedback points) and have reach about 21 total feedback points. Nothing to retire on, but it's like getting an extra 10% off every electronics purchase we've made this year :) A few things I've learned in the process:
* Don't take a request for an early sale, either on eBay or CraigsList. These people are trying to get a great bargain by preying on the seller's anxiety and buying at a lowball price.
* Include a little note in each shipment thanking they buyer for their sale and asking for feedback. This increased my feedback rate from 40% to 90% (roughly speaking).
* Build a cheap DIY photobox for getting better pictures. It also helps to have a wife with Photoshop skills to fix whitebalance, but you can still get better results starting with a basic photobox.
* Do your research when selling used DVDs. I've gotten $10+ for some. And lost money on others.
* Sealed Blu-rays are great sellers! Got $10+, after expenses, on some unopened discs I didn't want.
So what now? Are there any guides, books, or tips I could learn from to further enhance my sales? What helps increase the final selling price? I continue to sell some low-price items as much to get the feedback as to get the few dollars they bring. I think the next milestone is 100 points and I'm a long ways from that, but I'll keep chipping away at it.
