Cross-buy is a feature of some digital distribution systems available across multiple device platforms, where users who purchase a license to a specific piece of software are able to use the versions of the software for different device classes at no additional charge.
Sony Interactive Entertainment introduced cross-buy on PlayStation gaming platforms in August 2012: users who purchased select PlayStation 3 titles would be able to obtain ports for the portable PlayStation Vita console at no additional charge.

[6][7][8] Meta Quest, formerly Oculus has a similar concept of cross-buy for Virtual Reality (VR) experiences bought on the Oculus PC VR platform for the Rift and Rift S headsets.
PC VR Experiences which have subsequently appeared for the mobile virtual reality headsets Quest and Quest 2 can be made available to Quest/Quest 2 consumers without having to be bought a second time; however, the decision to support cross-buy lies with the game developers.
