No, that's not a typo. I don't know how Amazon pulled this stunt off, but they're letting you pre-order the Limited Edition of Battlefield 3, in downloadable form, for only $41.99 right now. That's $18 off the regular, $59.99 asking price, which is what EA currently charges on its Origin service.
The Limited Edition of the game includes a free expansion pack and some other goodies. In Amazon's words:
Pre-order Battlefield 3 - Limited Edition and receive the Amazon exclusive Dog Tag Pack for multiplayer use as well as the Battlefield 3: Back to Karkand expansion pack for free. The expansion includes four legendary maps from Battlefield 2 boldly re-imagined in the Frostbite 2 engine, as well as Battlefield 2 weapons, vehicles, and unique rewards. The code to access the exclusive content will be emailed to you the day your order is ready for download. Limit one per customer. Amazon reserves the right to change or terminate this promotion at any time. Offer valid when shipped and sold by Amazon.com.
That's quite a bargain for $41.99, especially since I wouldn't be surprised to see the non-Limited edition sell for $59.99 after the game comes out on October 25. Considering how much fun I've had with the BF3 beta,
I think I'm gonna have to pick this one up. Update: Too bad; the offer appears to be U.S.-only.
