Are any of these titles rare???

[ulri4651]

Okay, at my local bestbuy tonight I found the following blu-ray titles and was just wondering if somebody out there could help with which ones are rare/hard to find. They had the following:

Aeon Flux (ONE copy)
Babel (TWO copies)
Black Snake Moan (ONE copy)
Coming To America (ONE copy)
Disturbia (multiple copies)
Four Brothers (multiple copies)
Flags of our Fathers (ONE copy)
Nacho Libre (multiple copies)

I went ahead and picked up all of them except Four Brothers and Babel. Should I go back and get them at retail? And did I get lucky and find myself any rare gems? I thought Black Snake and Coming to America were supposed to be pretty rare but I'm not sure about the others. Thanks in advance!
