Well fortunately I watch a significant amount of late night TV (so any typos are due to Top Chef distracting me.) Anyhoo, I saw a commercial last night that Old Navy is having up to 40% off March 31-April 7th in stores. Figures they aren’t specific at all about what is actually on sale but it might be worth a look.
I was trying to dig up more information on the sale and found nothing- but I did find a 15% off Old Navy coupon for any one item. The coupon excludes clearance merchandise.
It looks like they also have a sale at Oldnavy.com with up to 40% off some items as well. Shipping is free on a $50 order.
