Great way to sell things douche.
So you know. Since your on the internet, with people that you will NEVER see in real life, maybe you should give them a little more information, on yourself and products to make them feel better about buying from you.
So..
1. Get pics of products. Preferably with a piece of paper with your SN and date.
2. Explain everythign as good as you can. Show whats bad, and whats good.
3. Provide any referances you may have online.
Ebay, other forums, etc.
4. Answer questions and comments with courtesy and professionally. In other words, dont be a douche.
5. And if you actually do all those things correctly, and someone actually wants to buy something, then ship it out as soon as you have payment.
