Sony will no longer allow retailers to sell digital codes for games, add-on cards and PSN$ cards will remain

I think this is more so a response from Sony to retailers, because (for example) best buy has been reducing shelf space for sony product (gaming in general) quite a bit to the point theres not enough room to represent all the games in stock on the shelf, nor do we put out promotional shippers because of floorspace for higher profit products like TV's, headphones etc. in short, retailers outside of gamestop have more revenue and profits to earn on other products than gaming, so the investment is not there.
