Stacksocial is back with another educational promotion, they are offering a prepaid 5-year subscription to the Polaroid University Video Classes for $25. This is a one-time payment that gets you five year access to their online classes, which you can watch via a web browser or their iPhone app. You can see details and previews at their website.
If you instead prefer a shorter term, a 1-year subscription is available as either a digital download or a gift-box delivered by mail for $20 through Amazon. Pay attention to the listing – download vs box.
