If you receive Old Navy emails, check your emails for a “Mystery Offer: You Could Save Up to 50%!” email that would have come in last night. The email contains a unique, one time use code that will be worth 15%, 20%, 40% or even 50% off your entire purchase. The last time they had one of these we scored a 50% off coupon and got some great deals. Sadly, I only got a 15% off this time, but let me know if you have better luck.
Old Navy also has a free shipping promo good through August 7th when you spend $50 ore more. Just use coupon code ONSPEND50 at checkout.
