An online merchant may lack a product of their own to sell and may purchase PLR media as a substitute. Typically, the product takes the form of an e-book or software. The PLR-reseller modifies the contents of an e-book and resells it under their own name. PLR software may perform various functions such as scraping Craigslist for wanted ads or managing email marketing. In short, a PLR-producer sells content to a PLR-reseller who modifies and sells it to a customer who may or may not be a PLR-reseller as well.
