I really do love Old Navy, they always have awesome deals and really cute clothes! Thanks to Oprah, there is a great coupon out for this weekend, Friday, May 13 - Sunday, May 15, 2011. (See, not everything is bad luck on Friday the 13th!)
The coupon is good for 50% off of one regular priced item. Here's the fine print:
*Offer valid from 05/13/2011 through 05/15/2011 at Old Navy stores in the US and Canada. Not valid online. Discount applies to regular priced merchandise only, not to GiftCards. Coupon is good for one time use and must be surrendered at time of purchase. Limit one coupon per customer per transaction. Not responsible for lost or stolen coupons. No adjustments on previous purchases. Cannot be combined with other offers or discounts including Gap Inc. employee discount.
It's a PDF and it looks like you can print it as much as you like, so share it with your friends! Happy shopping!
