I am unsure if anyone here has posted this, however two weeks ago, Walmart's web-site added new titles for pre-order, including none other than Equestrian Girls. Not only is there a DVD of the featured film, but also a Blu-ray. It is currently un-known what bonus context is included and if there will be any retailer exclusives attached. But it is stated to arrive to stores on August sixth!
Here are links to both the DVD and Blu-ray, pre-orders are open!
