Gift of Screws album sales

[Skyveris]

I'm curious as to how many units Gift of Screws has moved to date. I do know that the album debuted at #47 on the Billboards charts and that it deservedly earned the plaudits of the music critics. GOS is such a stellar album from my absolute favorite guitarist and I hope upon hope that it's selling reasonably well. Please post sales figures if known to you. Thank you.
