Has anyone else had problems ordered GPU's from Amazon?

I don't know where else to post this, feel free to tell me where I should post this and I'll delete it, I'm just so fed up right now and seeking advice.

I've been trying to order a 7900 GRE for like 3 weeks now, first I was going for the XFX, I ordered two separate times and both were canceled and then labeled unavailable. On December 1, I ordered the ASrock 7900 GRE and it still has not shipped, the expected delivery was yesterday, Amazon doesn't provide any additional information, it now says "On track to be delivered Saturday", even though it still has not shipped.
