I got it from Maximumpc member leakytire.
He is a computer seller who had someone back out on a deal with him for the chip, so I think he is giving me that chip at cost, $375. There were some WESTERN UNION fees that made it for a total of $412.
I get the full three year warranty and all.
This is setting off all kinds of red flags for me - I hate to jump to conclusions, but without further information, it appears as though you got scammed:
1) Looks like you were contacted privately by a member whom you've had no previous communication with (outside of your transaction).
2) The price on the 4400+ X2 is unrealistically low. It could have been resold for $75-$100 more than what you paid, if it was legit.
3) Western Union was involved, which is the preferred method of payment for scammers.
Were you contacted via PM and do you have a link to this member's profile? I'm going to be gone for most of this evening but, pending your response, I've put in a request for others to hopefully step in and let you know what limited options you have to work with, if this indeed does turn out to be a scam.
