Query: Wonderful Sandisk Service

A couple of months ago I bought this wonderful mp3 player. Of course Amazon's shipping went smoothly and the little thing works like a charm. Recently though I lost my earphones, and thought that I could just go online and buy them. Not as easy as that. I could find them no where and I loved these, they are very comfortable and have great sound quality. So I called up Sandisk Support and they are mailing me a FREE pair. I just really want to thank Sandisk for all their love and support, I think the company is just great.
