At my local Super Wal-Mart I missed out on both the Emerson 32" and 40" TV. They had 2 isles closed with these TV's stocked at least 10 high. Anyways, they had LONG in-store lines for both and were handing out tickets to be able to purchase. Way more people in each line than their available stock.
My local Wal-Mart ad said that if either item sold out within the hour they would offer a Guarantee Card for the item ensuring the item will be shipped to the store for you before Christmas. My local store didn't make the offer to anyone in line that didn't get a ticket.
I'm now hoping to get the 50" Emerson but from what I've read they have stocked fewer of these than they did the 32" and 40" TV. My advise, get in line as soon as you can!
Here's the specs for the Emerson 50" LC501EM3 TV.....
