Required 8GB Sandisk-Cards

RFQ Details

I am interested in these 8GB Sandisk-cards. Could you please send me an offer for 100 of these cards. And if you can make me a lower price apiece, then for 200 and 500 too. I hope I can sell them profitably. Then I would order more and regularly. But there some more short questions. First of all, are these cards assured if you send them to my office in Germany? And secondly, must I pay some taxes at the German duty? Kindly contact me as earliest.
Thanks
