Just went to the site, they have a banner for Hairspray, regular, 2-disc, and Blu-ray versions. Pre-order and get other musicals 'for as low as' $4.95. The link doesn't seem to be working for the 2-disc or Blu-ray pages (just comes up as a blank page), but I am very excited anyway! There is a trailer on the regular edition DVD page though.

Loved it!

Additionally, if you type in "Hairspray" in the search box, you only get the original film and calendar - I assume it will be working soon...

Edit: It is now working!
