Thanks so far, they are helpful suggestions. I don't want to work outside ebay rules and I have a couple of the items available.
If I give someone my paypal ID is there any way that they can get into my account?
But the gist is, after the auction, highest bidder gets it. If I want to sell the others outside of e-bay make sure the money is in my account before I dispatch. Once someone has sent a payment by western union or paypal is there any way that they can revoke payment?
Sorry for these questions but I've never used ebay before today and I'm paranoid that everyone is just trying to bleed me dry

Maybe I'm of too nervous a disposition...
