Over at Amazon.com is showing that the Ex List will be available on DVD, but you have to sign up for email notification to recieve an Alert for when it will be released.
Sorry to burst your bubble, but The Ex-List is not being released on DVD anytime soon as of now.
Amazon.com does the whole "Want us to e-mail you when this item becomes available?" for any title (movie, television show, ect.) that has previously been released (in movie theaters and on television) that have not been given a release date.
The network has clearly stated that The Ex-List will not be released on DVD.
