I have bought and sold on here a lot. Most everyone is honest, but this is online and there are risks. Make sure you check the Traders Feedback section on archerytalk. When a buyer is interested you can check his feedback before you close the deal.
If they do not have any feedback the best you can do is solicit a name, address and number. Confirm it online by doing a name search in
www.whitepages.com
Also, NEVER ship anything until the money is in hand and cleared. I don't care how fast they want it.
There just some of the excersises I go through. Best of Luck! This is a great place to buy and sell.
