I just mean, if I go ahead and pre-order it, will everything be peachy, or will it get screwed up down the road?
Hard to say. I rarely pre-order anything from Amazon because I've heard too many stories of them screwing orders up and either not getting the album out on time or worse. It doesn't usually happen, but it has happened enough that I don't trust them even though I personally haven't gotten burned by them.
On the other hand, I've had a great experience with CM Distro. I ordered the Queensryche special edition. I guess there was a production glitch where the autographed poster that was supposed to be part of the package got delayed. So rather than delay getting the preorders out on time, they shipped the rest of the package first, and just shipped the posters later once they came in. They not only got the CD out on time, but most people in the U.S. at least got theirs a week early. GREAT customer service.
I've been fine with Amazon on regular orders. Then again, I usually just pick up albums at the brick & mortar stores unless they aren't easily available online, or if there is some special incentive to doing an online pre-order (e.g. getting the album early, a special edition that isn't otherwise available, free advance digital download, etc.).
