All files on our MarketPlace have 2 license types. A regular license and an extended license. When you purchase an file, you are actually purchasing a license to use that file. Most of the time when you buy a file a Regular license will be sufficient for using it in your project.
However in some cases you may need to buy an Extended license. When and how is explained below. 

Regular License

The regular license allows you to use a file within a project of your own or on behalf of a client. For example, you could use a file purchased under a regular license in a website, a presentation, a promotional video, a poster or a free game. For web content a regular license is suitable for use on a single domain or single subdomain or single directory.
For most buyers the regular license is sufficient.

The main thing you cannot do is offer the file up for resale either on its own or as part of a project. So you can use the file in a free game, but not in a game that is on sale. You can use the item in a website, but not in a web template that you sell.

Extended License

This license is more expensive than the regular license. An extended license lets you use a file in something that will be sold. For example, you could use a file purchased under an extended license in a DVD release for sale, in a game for sale, or on a t-shirt or poster for sale. An extended license is also appropriate for people looking to offer a web template to many users such as on multiple domains, subdomains or sub directories.

An extended license does NOT allow you to resell the file by itself. You may only incorporate the item into a larger work that is then sold. The original item will always remain the property of the author.
