Amazon has withdrawn from sale all PlayStation Network content including prepaid cards, without explanation.
"We have no announcements regarding this change in selection, however we can confirm that Amazon Digital Video Game Downloads is not currently offering Playstation Network Online Game Codes and Points Cards," Amazon told PSN Stores when asked about the removal.
Links to the PSN content node have vanished from Amazon's PlayStation 3 category, and the URL now sports a blank page.
Existing product pages show a "currently unavailable" message, but previously purchased content can still be redeemed.
Sony is yet to offer comment.
