The employees are aware many people wait until after the first day of school to buy their supplies because teachers often add items to the list.
Chris Villalobos, an employee at the Office Depot, says the hours while children are in school is the calm before the storm because when the parents leave work it's wall to wall customers for the store.
"This is our black friday this is what we live fore every year," said Villalobos.
Office depot will be open until 11 all week and other stores are also stocked with school supplies.
