When you buy a digital product (whether it be an ebook, MP3 audio file, video, or software script) you will receive a product license with that product. That license will give you Private Label Rights (PLR), Master Resale Rights (MRR), Resale Rights (RR), or Personal Use Only Rights.

Products that come with Private Label Rights are products that may be re-sold to others and you keep 100% of the profits. You are allowed to alter the product however you see fit. You also may claim that you are the author, but you can't claim the copyright to the product. Depending on the terms of the license, you may or may not pass on the PLR to the purchaser.

Products that come with Master Resell Rights may be re-sold to others and you keep 100% of the profits. You may also pass along Resell Rights to those products to others if you choose to do so.

Products that come with Resell Rights may be re-sold to others and you keep 100% of the profits. However, you may NOT pass along Resell Rights to those products to others.

Products that come with Personal Use Only Rights (User Rights) may NOT be re-sold to others nor may you pass along Rights to those products to others. As the name suggests though, you are allowed to use the product.

Thanks,
