Went into blockbuster today, which is closing shop soon, and picked up these DVD's for a dolla each.
2 Sonic Underground DVDs
Super Mario Super Show (Mario out west)
The Collector (good movie IMO)
So, I ask them about store shelving units, and they have one in their office that's perfect for DVDs. About... 7.5 feet tall, 4 feet wide, and about 6 inches deep. I'll be hauling it very soon (possibly tomorrow) for $25.

Finally, an awesome to the ceiling shelving unit for when I get ready for Onion casing!
