Accepting CASH payments is a violation of Ebay's Safe Payments Policy.  Surprised???  Most ebayers are.  The only exception is items that the buyer PICKS  UP in person. If you accept cash payments through the mail you are leaving yourself wide open for a world of hurt.  ANYONE can report you to Ebay for this violation at any time.  If that happens, Ebay can, and will, cancel ALL of your listings without warning, whether you have 5 items listed or 5,000.  When they do this you will NOT be able to go to the completed items section and simply RE-LIST the items without cash as an option because the items will no longer exist ANYWHERE on Ebay.   They will have vanished into the boundless black hole of bureaucratic absurdity.  You will have to START OVER FROM SCRATCH.  So, the moral of the story is ... go change all of your listings RIGHT NOW, before you become some disgruntled ebayer's next victim.  It would also be a good idea to go to Ebay's Safe Payments Policy pages and read every single word.
