Take a look at the video below! When you're logged in at www.drinkhydrant.com/account/login, you'll see an "edit shipment" dropdown. Click there and scroll to the bottom, you'll see the option to "apply discount".
There, another box will pop up where you enter your discount code.
If the code won't apply, double-check to make sure the discount is valid on subscriptions.
Reach out to our team (email@example.com) with the discount code if you'd like our help applying it!
