I have it and honestly it isn't worth the postage. It's about 8 minutes long and it's not even a planning DVD, it's an ad for the 50th. Offers no info for trip planning. I blinked and missed most of it
If you have the DVD for WDW there is a section on DL which is as long as people say the DL planning video is. Maybe you could get the WDW video and look for the DL section.
