C: Frank, please, that is actually our best offer! I think it is very competitive in Germany. Frank: Joking? You quoted me EUR2.35, but my competitor bought from a middle man in Austria, just EUR2.15！ C: Hey, I also wanna support you to expand your market, but the price...

If ok, I'll send you PI right now. Frank: That's great! But if using super hey duty battery, the quality maybe weak. C: Well, just changing the printing, but keep alkaline ones, EUR2.15/pc, okay?
