5/1 through 5/2, OldNavy.com is going to be having the 30% off as well as the in store sale when you use the code ONBIG30!
There will be a flat shipping charge of $7.00 on all orders so this is an awesome way to save! If you have a friend locally that you can order together and ship to one address....you might save even more.
Be sure to check the clearance online. This is for 2 days only so make sure to get your shopping in before Monday.
While shopping online is good, shopping in store where you can find some great clearance deals and enjoy no shipping cost is where I feel the best deals are to be had.
