It probably was shipped and UPS has not updated the tracking number yet. I receive the packages a lot of the time before newegg e-mails me a tracking number
Unless......... you did the Egg saver shipment. If this was the shipping method, I suggest nightly prayers and a great deal of hope. It will show up within 14 days
It would have to be in the sun for a really long time before the normal heat of the day would hurt it.
Direct sunlight on the video card would be a different story. Your video card however will be in its own box in another box surrounded by some packaging material. you don't have any worries
Speaking of Newegg orders. I'm getting really fed up with how they package HDD's They wrap them in bubble wrap, but the wrapping is so tight that the bubbles on one edge are always busted it seems. So one side of the HDD is open to damage from the bumps and dings of shipment. Has anyone else noticed this?
