Rules Regarding Selling a CPAP?

Is this a "no-no" as far as this forum is concerned? I have a Resmed AirMini that I simply could not use after about 5 nights. Would like to try and get at least *some* of my money back. (Supplier does not take returns.)

It is acceptable for forum members, who use cpap themselves or had a family member who was a user, to offer up for sale their unwanted stuff.

Dealers or retailers.....not acceptable and will be considered as spam and deleted.
This forum isn't the place for an online list of items for sale. It's not a personal craigslist ad place.

Thanks! I didn't want to ruffle any feathers so thought I better check first! I will start a new thread for what I have.
