Q&A: Should I wait to buy mass effect 3 or settle for regular version?

All of the places to pre-order the limited edition version of mass effect 3 are sold out. Should I wait till the game comes out to acquire the limited edition or just pre-order the standard version and give up on trying to get the limited edition?
And no, I’ve tried gamestop, amazon, bestbuy, target, walmart, origin. They are all sold out.
