Help me out - I'm looking to start selling some of my cards on eBay to build up at least a little bit of paypal (probably to buy more cards).

When doing so, what are good things to do with the listing?

Also, how much is appropriate to charge for shipping?

Finally, my rating on eBay is only 6 because I just started with the buying. How much will that affect any potential sales? Should I offer free cards or free shipping to help attract buyers. I don't mind giving away free star cards/insert cards if it helps.

Thanks for any and all help with this...
