I ordered 4 copies of this (I always order extras to hopefully ensure at least 1 good copy) from Amazon Canada on Feb. 21st. The price at the time was $33.99. I noticed recently that my pre-order total before taxes is now $101.97 which works out to $25.49 per copy. Perhaps the price dropped there at some point.
The listing page now states that it's "Currently unavailable. We don't know when or if this item will be back in stock."
Anybody ordering it from Best Buy may want to keep an eye on it in case it comes back in stock for a possible price match.
I have an order in with Best Buy now as well at the $29.99 price. I would prefer to get this from Best Buy because Amazon's packaging is awful as some of you may know. My last order of 4 copies of a steelbook arrived in a single brown paper bag type of mailer a couple of weeks ago.
