OK, as someone who has a relative that is a department manager at WM I can offer a little info. on the whole "line" issue this year.
1. Most stores have gone to the "Clean Store" program where there are no longer pallets or 4-ways in the middle of their large aisles. Because of this they will not be having pallets out for Black Friday either.
2. All small items, such as games, toasters, etc. will be stocked on an end-cap (the end of an individual aisle that faces the main aisle). These will will be guarded by employees as usual and there's not as much space to gather aroun dan end-cap as there was around the pallets.
3. All large or "hot" items will have an individual designated line. Each person in the line will be allowed 1 item from that line (if you want items from 5 lines you'll need other people in the other lines for you). The employees are also only allowed to line up as many people as they have items for.....So, say they have 10 TV's and you want in that line---once they have 10 people in line they will cut the line off, an emplyee will stand at the end of the line and advise any new people that there are no more items available. Once the sale starts and it's your turn, you'll be given a ticket that you can take to the register and pay for your item, then once paid for you have to drive around to the back of the store to pick that item up.
Of course, like we all know from past experiences not all stores follow the rules they've been given and some choose to do things their own way. However, these are the rules that have been provided to the managment at WM, so in most stores you may see it happen this way.
