***update*** I was told by one of my friends that works at Old Navy that you have to show your high school or college ID to get the discount. I don't know if it's for all locations, so you may want to call your local store and find out more details.
School will be starting up again pretty soon, so it's time to get some school shopping done. Head on over to Old Navy this weekend and save 25% off your entire purchase! This in-store sale is good until Sunday (7/25).
