ebay's t+c's state that you MUST use paypal as a payment option

which is why it's gone down the pan for sellers

whatever you sell though, just put that you won't be posting it as the buyer will have to collect and pay cash there and then and it should be ok

but still put paypal as an option for a small non refundable deposit and then put it a pound or the like just to keep the bankers at ebay happy
