Three more days left until the Group Buy ends (February 20, 2014). You can sign up now and you have until the last day of February to complete your purchase (basically, when you sign up, you're promising to buy something).
For those unfamiliar with Kirk Hunter Studios orchestral libraries, they are sample libraries formatted for KONTAKT, exs24 and one library, Pop/Rock Strings includes the KONTAKT Player, that doesn't require you to own a sampler and qualifies you for special upgrade pricing if you decide you want to purchase the full version of KONTAKT.
