Change payment method for active auction listing ?

[myrtle-22]

I'm new to this and would be pleased to have some advice.

The auction is underway for a relatively high value item which is  listed as "Cash on collection" . My problem is that I'm getting bidders from the other end of the country.

I seem to have listed Paypal and credit/debit cards etc as "acceptable" methods of payment as well as " Cash on Collection" as "acceptable".

At  this stage in the process can I change the payment methods on my listing to "Cash on collection" only ?

What should I do if the winning bidder is not willing/able  to do cash on collection ?

You cannot revise and in any event you have to offer PayPal but can say cash on collection preferred.
