Centralized / Omnibus order (Sammelbestellung) of fairphone and spareparts to Berlin, like batteries

Hi everybody! I just wanted to get a new battery for my FP1U and saw that the battery costs 17 something € but shipping is more than half that price, 11€. I thought maybe we could organizw a shipping for more people then we can share the shipping price. Would anybody be interested? Thanks, Kej.
