I bought an iMac on Thursday May 07 from my local campus in Reno Nv. I did not get any kind of tracking number. I want to know what kind of wait should I be anticipating? It said 3-5 days shipping on Thursday, and now says "same day shipping". So how long do computers take to get to their destinations on average? Is there a chance I will get a call next week? I did upgrade the hard drive (don't know if it matters).
