Where to buy credit for the Blau network

Hello,

I am newcomer to Berlin and to the forums too. I have bought a Blau SIM card because I will be in Berlin for half a year, however, I don't know where I could buy credit for it once I run out of the initial credit, since I have not seen it at any place where can I buy it. I mean, you can find almost everywhere T-Mobile, Vodafone, Eplus cards, but not Blau. I bought the SIM card at a Saturn store, but it does not sell "recharge cards".

Do you know where I can buy it? I live in Friedrichshain, but it is ok even if it is far from there.

Thanks in advance.
