wow, I hadn't researched in a while, but that looks sketchy. I purchased one that cheap some time around 2011 and the company ended up having certs revoked and went out of business, and the next best thing I found was digicert at a fraction of the cost of the comodo and the like.

they do have EV for $350/annual or $750/3 year cert so I might try that it is certainly cheaper than digicert.

and yes EV is good for more than drivers, it allows EXEs to bypass smartscreen prompts that would otherwise trigger on standard certs that have to go through reputation checks in smartscreen.
