Amazon’s new “Subscribe & Save” service lets you sign up to receive shipments of certain goods on a regular basis, meaning that now it’s possible to subscribe to your toilet paper. Or cereal. Or Priolsec. They’re also offering a 15% discount to subscribers. You can choose whether to have the items shipped once every one, two, three or six months. Shipping is free. The service also sends out emails reminding you of an upcoming shipment, with an option to cancel. GTPD: Getting toilet paper done. Nice!
