So i just placed my first order with good express which provides free shipping (two day) and they have $30 off first order.
So I picked up the 6TB version which was on sale for $169.00 - $30 = $139.00 + Tax
Pretty nice to add another 6TB drive to my QNAP which is running this same model to keep them the same. I rarely see these get below $180 so $139 was no brainer
*Just click on thru to cart and under promo codes it should show the "NEW20" which is 20% off up to $30.
