Here's Toothbrush Subscriptions story of how it works:
A Toothbrush Subscription is very simple. The first thing you do is choose a toothbrush that best suits you. We carry a selection of high quality manual toothbrushes. Once you add your toothbrush to your shopping cart you will choose how often you want to have that fresh toothbrush automatically delivered to your door (every 1, 2, or 3 months.)
Your first toothbrush will arrive within 3-8 business days, via snail mail and then a fresh toothbrush will arrive again, automatically, on the schedule you set (every 3 months for example.)
You can choose just one toothbrush or as many as you like. There is no limit. It's that simple!
