Dell Home offers the Dell Virtual Reality Visor with Controllers for $360.99. Coupon code "EXTRA10" cuts it to $324.89. With free shipping, that's the lowest price we could find by $124. (We saw it a month ago for $7 more but it included a $50 Dell gift card.) It's compatible with a selection of Inspiron and XPS laptops and desktops and features a 1440x1440 resolution per eye, 90Hz refresh rate, 110° field-of-view, and Bluetooth.

Update: The price has increased at Dell Home; however, Cardinal Pro Express via Amazon offers it for $274.40 with free shipping.
