Nevada, Mo. -- A promotion at Wal-Mart got out of hand Friday morning when a woman was knocked down and the game console she was trying to buy was taken out of her hands by other shoppers -- twice. Lisa McVay was going to purchase an Xbox at the promotional price of $199 and had one in hand ready to buy when a woman came, pushed her to the ground and wrestled it away from her.

"I had an Xbox in my hand and this lady came and knocked me down," McVay said. "She was pretty big and she wrestled me around and pulled my hair and got it away from me. Then I managed to get another one and some guy came and did the same thing."

McVay said she was surprised by the lengths the people were willing to go to get the discounted items.

"I was truly shocked," McVay said. "It was like a frenzy. I couldn't believe adults were acting this way."

McVay said she would avoid such sales in the future -- the money saved wasn't worth it.

"It's worth paying a little extra to not have to go through that again," McVay said.

McVay said the trend seemed to be getting worse, with incidents becoming more frequent and more violent as time goes by.

"I think it's getting worse," McVay said. "You're hearing about this more and more. Someone could actually get seriously hurt at one of these sales."

It isn't just a Midwest or even American phenomenon, it is worldwide. Last year in England four shoppers needed urgent medical treatment at three separate branches of Next in the West Midlands after lines began to form in the early hours. Three people were taken to hospitals and one woman was treated at the scene.

According to the Associated Press, a worker was killed Friday morning in the mob of eager shoppers who crushed their way through the doors at a Long Island Wal-Mart. Reports say at least four other people were injured. The AP said that Wal-Mart Stores Inc., called the Long Island incident at "tragic situation."

Ellen Davis, a spokeswoman at National Retail Federation, told the AP the group knew of no other incident where a retail employee has died working on the day after Thanksgiving.
