Hi @barryo,
According to ThemeForest terms, the main difference is that under the Regular License, your end product (incorporating the purchased item) is distributed for free, whereas under the Extended License your end product may be sold or accessed by paying users. In both cases, the licensing is relative to one website (or client project).
In summary, our understanding is that you can either:
– Buy a new license for each new client project as long as the built online service is not sold to end users, or
– Buy a new extended license for each new client project if the built online service is accessed by end users in exchange for a fee.
