i have a question

Hi i need help with the market trade for characters i got 4 characters on frostwolf MoP if i sell one of the characters will all the mounts go with the character and will the mounts be removed from my other characters or will the mount stay and what if i sell more then one character will the mounts go with them or only with the first character i sell ???
and do realy ppl buy characters for like 300 and more coiens cuz it sems not realistic price its so much money do realy ppl pay dat much.
thx in advance

All mounts bound to that character will go. So for example: Let's say you go Baron Rivendares Mount on your Deathknight, but aside from the Baron's moutn you have the Archerus Charger and that's it. But your other toons have many other mounts that they attained. If your DK leaves your account you lose The Barons Mount, and Archerus Charger (of course), but that's it.

AT least that's how it worked in retail if you deleted a toon. I once deleted my priest and lost my Ashes of Alar, so I had to have it undeleted to gain it back.
