It says I don’t have an account but I have a subscription?
First thing's first: please double check the email address you used to sign up for your subscription is the one you're using to try logging in.
If it still says you don't have an account, it is possible to check out with a subscription as a guest! So you might not necessarily have a HEATONIST.com account if you receive our sub boxes.
