I don't think you can call it out of stock,can you?No offense.But personally speaking,I only trust one who tells the truth.
Are you sure those are not resellers?
They are retailers indeed,I use "retailers" instead of “resellers” to avoid any possible ambiguity .Also,one of the store is run by Cherry China officially,not personally,not by Tmall,taobao or Jack Ma.And there, the keyset "kc520" is still in stock(If I made a mistake,I will apologize.)Xiandian use this to prove that the keyset is welcome by Chinese keyboard enthusiasts,but the fact is that most of them won't pay for a keyset of 125keys,which will cost 999CNY=155USD. Fortunately,all shipping fees are included.Besides,as a group organizer,Xiaodian is reliable.Once you pay,you will definitely get what you purchase within a few months,not worrying about any risk.
