Just found this monitor in store for $300 and couldn't find it on Costco's website at all.
Everywhere else this monitor is $400 (Walmart, Beach Camera, B&H, Samsung.com etc).
Costco lists it at 75Hz, all others say it's a 60Hz monitor. Will update when I open it.

Checks out a few of my "needs" so I grabbed one to see if my missing "wants" will make me return it.
