Is this why there are some sellers on ebay that are
absolutely hostile
to anything paypal? I even had one seller that would only accept
paypal coupled to a bank account, not a credit card (although how they
could tell I don't know).
In the second instance, it was probably because (AFAIK) PayPal nicks you a chunk of
change per transaction if you accept credit card based payments.
First instance is probably because they are reticent about giving a corporation
permission to muck about in their bank accounts.
