Ok, I hope I don't come across rude or snotty...
I work for Walmart. It really bothers me how some associates get on this and give inaccurate information to potential customers. It also bothers me that this information is often portrayed as fact. Over the past few years, Walmart has made an extensive effort to clean up its "Black Friday" image. Extensive educational material is often available to associates on what our plan for Black Friday is. However, I have often found that many managers simply DO NOT pass this info on to associates, which in turn give bad information to our customers.
With that said, here is what is happening this year...
Walmart has faced increasingly stiff competition from other retailers over the past few years. Walmart is trying to go on the offensive this year. Walmart will still hold its annual Black Friday sale starting at 5am as it always does with doorbusters and hot deals. That will not change, nor will it ever. This year, however, Walmart is going to try and lure in more customers by offering a sale that will start at 12:01am on Black Friday. This is in response to competitors over the past few years trying to go earlier and earlier on their sales (malls opening at midnight, JCP and others opening at 4am, etc).
Now, with all of that said, some of Danigirl55's post was a bit accurate, though not completely. I just think she was confusing the main 5am sale, with other information we have received. Walmart, in order to prevent any fatalities from occuring as did a few years back, is doing what it did last year. 24-hour stores will of course be open. (I will admit there still is confusion on the non-24 hour stores, so I'm not going to give any info on those stores). Walmart will have its Black Friday doorbusters spaced with line-up points around the store (marked with large helium balloons). These lines will be for the hot, limited quantity doorbusters like the TVs, laptops, etc.
Last year there was a ton of confusion at the store-level as to how the lines would operate. Some stores let you line up as early as you could get there at the numbered balloons and once you got a wrist-band you could wander around until you were ready to pay, the wrist-band guaranteed you would get an item (the wristband quantity matched the store inventory). Then, some managers made customers stay in line at one item until 5am and many missed out on other items. As much as it was cleaned up and better organized from previous years it often ended up a day-of decision by store managers.
Wow, I didn't really mean to type that much!
Bottom line...
TWO SALES THIS YEAR ON BF. One, starts at 12:01am and one starts at 5am (traditional BF sale).
I hope that helps.
