The issue you have with Ebay is that you need to sell volume and get up to a power seller status where you get discounts on your fees. Also once you start moving high volume amounts of money through paypal they lower the fees for accepting payments.
If you are just selling x box live cards you are going to struggle and i would suggest you look for somrthing else to complement them. You will find there are dropshippers if you do not have the money to buy stock straight off.
Also look at an ebay shop as the listing fees drop with a shop but you need to be selling enough to cover the fee for the shop.
Ebay is now sadly about volume sellers and if you want to sell small quantity or low value items you will struggle to compete with the big buyers.
I would suggest that you do your reasearch on other sellers on ebay and offer something they dont. Also get a template for your listings it will make a big diffrence so do ending times and listing times as well as catagory.
