Invest

First of all pay off your bills , specially a credit card debt because later you'll have to pay a higher interest. maybe

I don't know if trying to sell stuff on ebay is the way to go. I think gabriwa's advice about paying your bills makes a lot of sense. If you have money left over, there are a number of ways you can invest your money , though 500 dollars aren't much to start with.

If you wanted to take a more risky road, you could try the stock market, though you should really find someone who knows something about this type of investment. You could also try more conservative investment plans such as bonds.

I suggest you go to  http://www.fool.com/investing.htm?ref=G02A02

This link will help you make some sense in the confusing world of investing. 

I personaly think that you should invest it.  A perfect Company to invest in is The INDI Trading Company, i opened my account on the websit (www.indiplan.com) and i recive 2.5% interest every month guaranteed on compounded interest.  and you will get double your money back in a few months time, try it.

I agree, that paying off any credit card debt would be the best thing to do and then you can consider investing. A great conservative investment would be a certificate of deposit (CD) at your local bank or credit union which would give you a guaranteed 4-5% interest. You can also consider no-load mutual funds of different types..at websites like trowe.price.com you can do some research and find funds you can invest in at as little as $50 a month or as much as you want more so its a good way to save incrementally. You do need to research the funds and see how much risk you want to take and what type of fund would be good for you. The best thing you can do for yourself is to really educate yourself on investment before putting down your hard earned money.
