If you're in the US, BN.com (website for Barnes & Noble) currently has the Shada DVD on sale for $23.99. That's online only. In stores it's full price - $40.
No idea how long this sale will last, but I ordered it this morning and it's shipped already.
It's pretty rare for B&N to have a decent price on DVDs. If you're looking for a deal (and the next cheapest place is Amazon at 31.99) now's a good time to pick it up!
