If the course is not right for you, ask for your money back within 30 days of the day you get your lessons and you will be refunded. To ask, email support@englishbudi.us from the address you bought with.
It is automatic. You do not need to sign up, pay or do anything except buy the course. When the course is updated, the new version is available in your account, and I will email you about it.
This applies whether you pay the pre-release price or the regular price. The 5 years start on the day you buy.
