Microsoft Store and Best Buy offer gift cards, now newegg is taking $15 off the price. Though newegg charges tax in NJ, still a great deal! Though shipping is three days I've heard some people get it on release day, depends where its shipping to I guess:
If you are still looking for a LE keep an eye out during the week before release. Usually that is when they release their remaining copies. Usually its just a few at a time so don't rely on that "e-mail me when available" thing. A mix of luck and good web stalking skills will score you a LE without fail.
haha maybe because it was posted July 14? Well the same promo has been coming and going for the SE on Newegg so I wouldn't be surprised if it comes back. Just this past weekend Newegg had a $12 discount promo for the SE. Code expired already though. So just be on the lookout from Newegg if you are looking for Halo 4 around the $45 price range. Got mine for $15 off on Newegg. Great deal!
