Deep Discount, that company again, has another great pre-order offer. They have Finding Nemo 3D, a 5-disc Blu-ray set for just $19.99. I imagine that's probably as cheap as it'll get, even with the use of any coupons. It comes out on December 4th, so plenty of time to cancel if you change your mind
They also have an offer to save an additional 10% off your next order when you share the links on twitter, facebook or email. See the right side of the page for that.
