If you don't mind me being the barer of bad news, JRUN is their product name. Posting it for sale is an act of bad faith and they may file a WIPO suit against you and try to take it.
Contacting them and trying to sell it to them is even worse.
You may want to remove this post since it will probably show up in a search engine and thus have the possibility of being used against you.
I am not a lawyer. This are just my thoughts from experience.
