It's on the Perusal page (the same page where you would order a perusal copy of a script). Go to the home page of "My MTI Account" (http://account.mtishows.com/login.asp) and mouse over the "Applications" tab. Click on "Apply for a Perusal," then scroll down to the "Reference Recordings" section. Type the name of the show you want into the search bar, then click on "Continue" at the bottom of the page. Continue to checkout.
