don't bother using it now until 1 month later.
if u buy an item from an origin town @ qty5000
you need to wait about 40 days to break even
and u need 2mil for trade permission as well.
say @qty5000 rug (1,500,000) u buy one
@qty4523 rug (1,6500,000) u sell it
1,6500,000 - 150,000 (10%tax) = 1,500,000 therefore u break even
u need 39 days 18hr for it to go down to qty4523 to break even
tip now is to wait for atleast a month before u start trading
