@Citriko - First off, welcome to the community! You might want to have a look at ebay.de, as Till has already mentioned, or you may ask someone for a budstick, if you know how to graft... However, if ordering a plant, you shouldn't overlook the shipping cost, which is usually in the same range, if not even a bit more expensive than a plant itself... Things like that, along with limited space for their overwintering, make me think twice before making an order, lately.
Have fun,
Igor
