You can also just jack up your shipping prices a 
certain percent to offset it.
This all boils down to ebay wanting to try VERY 
hard to squeeze PayPal out of business, and get 
people to use their annoying "Billpoint" service. 
Ebay cannot STAND the fact that PayPal has more 
customers. They are extremely greedy, they want 
ALL of the pie, they're not content with having a 
very large piece. Notice they don't go after 
people with Billpoint concerns, just Paypal.
(This has happened to me, too)
I will never use Billpoint if for no other reason 
than I find their over-advertisement of it 
extremely irritating, and who wants one company to 
have their fingers in THAT much of your "pie".
I would not want the same company that runs my 
auctions to also be my online financial service- 
it just seems like an invitation to trouble.
