For me, buying new is important since I figure coming from a BBV anything previously-viewed went through multiple hands but that's just me. Other people may have no problems with it since, unlike DVDs, BDs don't scratch. Stayed away from titles that I can get for $9.99 just about everywhere else so ended up getting the following:
Social Network $12.99 (too bad no $9.99 price at this store)
Avatar $12.99
Star Trek (3 disc) $9.99
The Notebook Limited Edition (for the missus plus I almost never pass on a Limited Edition at this price)
Robin Hood (2010) $9.99
The A-Team $9.99
They had 2 copies of Dark Night (w/ batpod) at the store I was at but had to passed since I had one copy already bought at a slightly higher price. Only other movie that caught my eye that debated whether to get or not is Unstoppable since I'm an action movie nut but since I spent too much already, I had to let it go.
