[if this is the wrong place, i'm sorry. i thought it was. place replace it]

Hey all!

My 3DO version of WC3 has a cracked disc 1 for a very long time, and i realy want to play it again (same with my SWC, has a scratchy disc).

Now, i think of buying those 2 games from Ebay when the oppertunity arives (lot of them) but i don't have experience with Ebay or related things.

I don't have a credit card, so i must get a Paypal acount? How do i bid on them, and pay for it? What are the do and donts? What are things i must keep in mind?

Can someone awnser my questions?

Thanks in advance!!!
