How do you sell mills?

I feel like an absolute retard asking this, but how exactly do you sell mills to other people? Like when people want to buy, lets say 50 mil for $100. How would you transfer the mil to their account?
Thanks.

 

Over bounty hunter, they come in and kill you while you have an expensive item on you. Read around the RuneScape general forum for several methods of transferring. Remember to always use a middleman and screen shot the trades for safety.

 

You can use bounty hunter method:

Or party pete's, this is where you buy rune plates.. and put them in party pete's ONE and a time, then pop the baloon's until you retreve the rune plate onto the other account(s)

 

Alright, thanks alot!
