Well, getting back on topic of being a cag...
Amazon has price matched: http://www.amazon.com/The-Bible-Epic-Miniseries/dp/B00AMR5LZA/ref=tmm_dvd_title_0?ie=UTF8&qid=1363093607&sr=8-2
From my experience, they do not offer release date delivery. They'll ship pretty much the day it's released, so it'll take a few days for you to get it.
http://www.amazon.com/Mass-Effect-3-Xbox-360/dp/B004FYEZMQ/ref=sr_1_1?ie=UTF8&qid=1334603262&sr=8-1
Looks like Amazon decided to match Best Buy's advertised price on Mass Effect 3.
