Sony Computer Entertainment America has begun selling PlayStation Network content via online retailer Amazon.com.
The service is so far only available in the US, and features over 200 items including new games such as Fat Princess and classics including SOCOM and Twisted Metal.
"We are excited to expand our current library of videogame platform downloads," said Paul Ryder, vice president of consumer electronics for Amazon.com.
"PlayStation Network games are an important addition and we plan to continue making it easier for customers to instantly enjoy new content as well as their favourite games from the comfort of their living rooms."
Amazon already sells WiiWare and Xbox Live titles through its online store.
