I'm going to buy Superbad on DVD when it comes out Dec. 4th, but I'm not sure whether or not I should get it online. I think I'm going to go with Amazon, but if I use the free super saver shipping will it ship on the 4th or before the release date so it arrives on the 4th? And if it won't in time, where offline can I get it for the lowest price? The main stores in my area are Walmart, Target and Costco. Which should I go with? http://www.amazon.com/Superbad-Unrated-Two-Disc-Jonah-Hill/dp/B000WZEZG8/ref=pd_bbs_sr_1?ie=UTF8&s=dvd&qid=1196318293&sr=8-1
