making money on items from gmshop

[Tsubor]

this is on a private server and uses the //gmshop function
its also a L2J server.

i cant say it will work for all servers for it may have been fixed or it may not have been.
the server i play on, it works on as of right now but may be fixed soon not sure.

now the server i play on, you open gmshop
you choose the events option from the main menu
you then scroll down to the bottom and buy the black party masks for like 100k
then take them to the trader and sell them for 300k

as of right now the red party masks work the same but only able to sell them for 125K and not 300k

there is also a glitch with the gmshop that after talking to the trader you can't buy from the gmshop,
just hit escape like 2 times and you should be able to use the gmshop again.
it should make you untarget the trader and allow you to use the gmshop with out a problem.
