Here is my 2 cents, they close both sides at 2 am. From 2 to 5 they move all the "HOT" items into the center aisles pallet after pallet. Then at a quarter till they get ready to reopen. A word of advice, go with someone, and stand at opposite entrances. They open one side at a time and it is usually the longer line. We are experts at this. Wife and I hit the 3 major stores and never get left out. But rest assured it is all chaos and mayhem.
