Arma 3 Exile duping

so i found a ''new way'' to dupe in exile most of the servers.
i made 1mill in like 5min of duping i gona make a tutorial from it soon until that check out this short video

Hey Iv seen this method used before but not really understood how to do it If you post a video or give me a private message and show me how to do it I would be very grateful

How do you actually do it?

Hope you get the video up soon!

Okay you really have to upload the whole process.

Can't you just tell us how to do it? you don't need to show us

So, no tutorial vid im guessing??

Wouldn't this be quite blatant considering you're selling the same item multiple times?
