Some unreasonable demands in here...last time I checked, Newegg doesn't email you when a price special goes away. Why would they be required to notify you of an expiring deal?
Newegg has clearly stated expiration times on their promotions. They also sell items they actually have in stock and deliver >95% on time. Would you like to pick another example?
The shell shocker deals have expiration times, but not price drops. Why do you think deals get marked dead on Slickdeals? Most of those never have any indication of when the promotion will end. I do not see how this is the vendor's problem that you were not able to get in on a deal.
It's unfortunate that you are not getting a response though. In my personal experience, all 3 of my orders I had were delivered ahead of schedule and all my email inquiries were addressed with a 24 hour turnaround time, max.
