For a very long time now, Amazon has kept A/V media items out of their Add On category. That is, you could buy A/V media items (CD,DVD) with free shipping if you have Prime, no matter what they cost. No longer. Today I noticed what seemed to be all media items being sold for less than $5 as Add On items. So now you'll need to bundle $25 worth of stuff to get them shipped free. End of another era.
