How can I pay via bank account? Which shop?

[thechef]

I'm from switzerland and have a bank account there, but I have no credit card and no paypal account.
Which online shops (I prefer shops in germany) allow me to buy the first episode via ebanking or all episodes via ebanking or 'cash on delivery' ('cash on delivery' is too expensive otherwise).

I don't care about localization(playing the english version in ANY case), boxed/downloadable etc, but it must run on linux.

I will buy each episode as soon as my requirements are met. (-> Never, if the requirements are never met )
Is that the case already for the first episode? I couldn't find enough information about a boxed version with linux support and no information on online shops, that provide my preferred payment methods.
