They had a handful of gift sets/collector's editions on sale for $20 before Christmas.
Frozen Planet
Life
It's a Wonderful Life
The Original Christmas Classics
White Christmas
The Wizard of Oz
Willy Wonka and the Chocolate Factory
List stolen from blu-ray.com. I picked up the Emerald Edition of The Wizard of Oz (not the giftset) for $20. Pretty good deals on Oz and Wonka if you can still find them.
