The 10% Off your entire purchase at Old Navy Coupon is still available on their Facebook Page. Coupon is valid through 7/3/13.
They are also having their $1 Flip Flop Sale on 6/29/13. There’s a limit of 5 per Customer, while supplies last. I’d get there early if you plan on buying some.
While on Facebook, don’t forget that you can follow me on Coupon Geek!
