I'd ordered the 9900K online and received a call a couple of days later to let me know the K series wasn't available but if I didn't need the iGPU I could have a 9900KF instead. The call was really nice, and I had no worries choosing the KF knowing that I should be fine with that, BUT I would have preferred the one I ordered, and assumed was available.
Please don't take this as a negative comment, it was all handled very nicely, I just think it's worth noting for future reference that if it's available on the website I should be shipped as such.
You guys do a great job, keep it up. :)
