Our Walmart is 24 hours, but last year was the first year they stayed open all night Thanksgiving night. Before they gave us donuts, coffee and full lists of every item on sale and where to find them. They had computers already in carts ready to go, you just ran to one and took it. It was a great way to do it.
My issue with staying open is people stand in line for 8 hours for one item you may not even get, and then you miss all the other bargains. Last year the laptops and computers had people waiting 8 hours. How do people with lives compete with that.
When they open the door at 5 you can run to the computers and then to the mp3 players and gameboys.
Gone are the times when each of us would grab three items for the three different shoppers in our group while someone else grabbed 3 tvs or dvd players.
