The Collector's Edition has previously been sold out, and getting a chance to grab one now is pretty amazing.
Wrath of the Lich King will be released next week at 12:01 a.m. on Thursday, November 13th. Amazon and other online retailers are "guaranteeing" that they'll deliver Wrath to you during the day of the 13th.
The Collector's Edition is selling for $69.99, and the regular edition is going for $39.99. We have previously covered the contents of the Collector's Edition.
We'll update this post once when we learn the CE's are again sold out.
Updated 6:45 p.m. EST: Sorry! Amazon is now once again sold out of the Collector's Edition.
