Unfortunately an active subscription order cannot currently be modified or combined into another one. In order to combine two subscriptions, you would need to cancel both of the subscriptions and then create a new order with the products you want to be shipped periodically to you.
If you would like to do that and update your current subscriptions:
- Log into your account at www.bulletproof.com
- Under 'My Account', click the 'My Subscriptions' option
- On the right hand side of the page, click the 'Edit' option. This will take you to the 'Subscription Information' page.
- Click 'Cancel' and then 'OK'
Then you can place a new order like you would normally and voila! The subscription order will be combined under the same cart on the same date.
