Lots of photos are the best - I look for photos when I buy, and post them when i sell.
I do post a lot of "buyer beware" because I am selling items I acquired via auction.
I list as professionally as possible, and post images of the questionable areas. I am not an expert in most of what I sell, so I request my buyers ask me specific questions.
CYA is always a good policy, but also honesty is always the best policy.
Always list anything you see that is a negative or a defect! I don't sell anything I wouldn't want to buy myself. n fact that is the biggest fight my girlfriend and I have. I buy to sell, she buys to keep!
The difference, I will sell anything. I buy things i want because I hope there are others out there that want the same things I like.
If I was rich, you all would have nothng to bid on!!!!
