Old Navy has some of the kid’s jeans priced as low as $10.00. Plus when you buy 2 pairs, you get $5.50 off. So, you can snag 2 pairs of jeans for only $4.50 each. They will most likely sell out quickly so you might not want to wait. You can head over here to check it out.
Don’t forget about Ebates where you can get 2% cash back.
