OralCare365 has a monthly program and they are offering up a nice freebie for a limited time.

Get 2 free toothbrushes AND free shipping from OralCare365. Visit OralCare365.com and add 2 toothbrushes to your cart. I chose “deliver every 3 months”.

At checkout enter the coupon code jan2free to make your total $0. You can sign up again and use coupon code twofree

You will need to enter a credit card number. After you get your first shipment you can cancel at no charge. However $2 for a toothbrush delivered isn’t a bad deal.
