Includes 3 reusable bags. If you purchase our Thermal Bag Subscription, then Farmer Ian will pack your order in the thermal bag for delivery, and the next time you order Farmer Ian will pack it in a 2nd thermal bag. We will request that you then leave out the 1st bag for Farmer Ian to sanitize. The subscription includes 3 bags, so that if you forget to leave your first bag out at any point we can still deliver your order in a thermal bag. We are offering these bags at cost, and do not profit off them.
