Every aisle was so crowded that it was shoulder to shoulder? That is packed in where you can barely move. That means there were thousands of people in the store at all times if the store was shoulder to shoulder - packed. I have never seen Walmart like that - closest is maybe couple weeks before Christmas.

I find it odd as I was there 3 times last week and was able to get in, get a few things without being packed in any aisle with a crowd of people and able to get out through the cash quite quickly. I have no idea how I was able to do that in a store that is packed shoulder to shoulder. I must have invisibility powers or I repel people and they scatter so I have space to move around!
