Thumb Score: +1

MicroCenter [microcenter.com] has the Acer 27" 4k monitor for $ 329.99 $ 170 off list price.

For comparison, Amazon [amazon.com] has the monitor for $ 434.99

Supports HDMI 2.0 and has 2 DisplayPort inputs, which is great for my needs of having multiple machines hooked up at the same time.

cons: no vesa

No tax for me, but I did have to pay for shipping at ~$ 30 for 2 monitors
