I came back the next day, and they proceeded to make me wait 20 minutes before telling me the guy who registers the SIM cards is not here today so you can't buy it today. I went to the Saturn store down the street and got my prepaid SIM for 10€. (Media Markt was going to charge me 20€). Go to Saturn store down the street
