Western Union Auction Payments should be able to 
work, as long as the buyer has a credit card (non-
Mastercard).  For a service fee, they'll send a 
money order for her to you, which you can then 
cash in for real money.

Most international sellers (even from Asia) on 
eBay accept this kind of payment so it should 
work for you in Europe.

Since the fee can be pricey, this service would 
work best on high-end auction items.

Otherwise, I think the other buyer should sign up 
for PayPal with her credit card, as long as your 
account accepts credit payments.
