IPC Store via Amazon has the MSI GTX 1060 AERO ITX 6G OC Graphic Cards GTX 1060 AERO ITX 6G OC for $309.11. Shipping is free and I'm guessing most won't be charged sales tax either.
IPC Store has reasonable ratings at Amazon. But, for those also interested Amazon is also taking pre-orders for the card at $322.28 (due in March 20th).
A little higher than some of the previous offers which were just under $300, but still a solid price in today's video card market.
