How do I add-on to my next box?

If you are a current subscriber and would like to add-on to your monthly shipment just follow the steps below:

  • Sign in to your account and then visit
  • In the add-on page, select the desired item(s) and click the ‘Add to Cart’ button
  • There will be an option to ship with your next MTB shipment (free shipping)
  • If you choose to add the item to your next shipment and you have multiple subscriptions, you will be asked which subscription you would like it to ship with
  • You will not be charged for the add-on items until your next box renews. Your add-on items will show at the top of your Membership & Subscriptions page! 

Please note: You will not be charged for your items until the 1st day of the following month. At that time, any available account credit will be charged first and the remaining balance will be charged to your payment method on file.
