How come 1 in 5 people in Wal-Mart and Sam's Club have PJ's on? Amber and I always see them, in masses!! This past Sunday morning we went to Sam's Club. I was curious why people were waiting outside and realized the store didn't open until 10am. A few minutes after 10am we enter and to my amazement I realize what the fuss is all about. These folks wake up, drive to Sam's club (while still in PJ's) to eat free samples for breakfast at 10am.
