Please no!! Communicating with buyers/sellers, reading descriptions and searching for items in 3 different languages is already enough trouble.
Someone in another part of Switzerland was the highest bidder in a recent auction of mine and he couldn't figure out how to pay with my IBAN

12 days later and us communicating in very bad French, he has finally paid me.
EDIT: actually, after looking at my bank account and translating his email, he has just paid at the post office, so still waiting.
