We'll send you the Exchange Box and within it you will find 2 full spare canisters along with a prepaid USPS shipping label. Save the box and prepaid USPS label within for future exchanges. When you've gone through two canisters use the Exchange Box to send 'em back and we'll deliver 2 refills at a members rate of $44.44. Reorder as frequently as you need with our refills on-demand.
*Make sure to always send back two (2) empties to get the member rate on your next exchange.
