Should I bother preordering the arkham origins collectors edition, or can I wait and still find one at a cheaper price?

I really want the collector's edition, but I don't wanna spend so much money on it. Does anyone think I'll be able to fimd one later down the road, at a cheaper price. And if so, about how long on average would it take? I've never bought a collector's edition of anything before, so I don't know how limited they are on average.
