The practice of Ebay to not allow cpap masks and certain accessories to be sold on this site is truly unfair and causes hardship among the persons that need these items and wish to save money over purchasing them from local suppliers in their areas.  The local suppliers charge outrageous prices for anything cpap related and although I have insurance, they jack up the price so that my co-pay is more than what I used to be able to buy the same thing on Ebay for.  I truly feel for the people that need these items and don't have insurance and can no longer buy them off Ebay.  It seems like Ebay is in bed with the big companies that charge the high prices or some respiratory therapy association in an attempt to make sure those of us who need these supplies pockets stay as empty as possible.  I see no reason why selling these things would be any risk to Ebay.  No more of a risk than selling a knife which can kill or a car whick can kill or dozens of other things available on this site. 

     If you are a cpap or bipap user and have been affected by this unfair money costing policy, let Ebay know it by writing to them, although it may fall on deaf ears.  In the meantime, you can put the word 'discount cpap' into a internet search engine and find all types of items at pretty good prices and the shipping is reasonable as well.
