CBD is having free standard shipping on orders of $35 or more. This offer ends on July 14, 2014 at 11:59 PM EDT. The notice I got for this said it was "Homeschool Free Shipping." I didn't notice any restrictions on what you could buy with the free shipping code. However, the notice did link to the homeschool side of CBD. So, here's the link to CBD/homeschool.
