ARUP, NewEgg has the 8700k in stock right now for ~$405. Also, not sure what part of KY you're in, but MicroCenter has them in their Cincinnati store for ~$380, if it's not too far to go - or maybe you know someone who lives near one of their stores who'd be willing to pick it up for you.
MicroCenter usually has better prices on CPUs than anyone, and also they offer 'bundle' discounts if you buy a CPU with a motherboard. It's usually a great deal; in fact I've been buying CPUs and motherboards there exclusively for many years now.
Good luck. And please check your PMs
