I found this over on the PDAbuzz discussions..

right now Dell is offering 20% off any accesories or software in their small biz store - that means that the Visor Edge or a Prism is only $320! a Deluxe is $160.. see http://www.dell.com/us/en/bsd/topics...htm?DGVCode=EM

It expires August 1st so hurry!
