Since I posted this last night I wanted to make sure that you didn’t miss this great deal!! Right now on Groupon, you can get a $20 Old Navy Voucher for just $10!!! You should be able to use this one on sale and clearance priced items. However, until I see mine post, I can’t tell you if it is considered a coupon or a gift certificate. If it is a coupon, you can not combine with other offers. But, if it turns out that it is a gift certificate, you should be able to!! Head here to find this deal!
