This may be pretty YMMV. I went into Walmart yesterday and noticed they put a bunch of Transformer 2 - Revenge of the Fallen Walmart Exclusive 2 Disc Big Screen Edition blus in the $5 display. I've only seen them at one Walmart, but it may be worth keeping an eye out for it. Here's the link to the specific edition.
