There are usually 4 flavors of rights you get with any kind of digital product on the internet.

1. Personal Rights (PR) – this allows you to use it for
yourself. Not my favorite.

2. Resell Rights (RR) – this allows you to re-sell personal
rights to your customers. Better but not good enough.

3. Master Resell Rights (MRR) – this allows you to pass on
re-sell rights to your customers which makes it an even
better selling point! I like this one

4. Private Label Rights (PLR) – this allows you to
*completely* change and customize the product as
though you made it yourself. A person favorite.
