i did the same trick onley with gems, harder to get but much more profit.. now i have so much gems that when I do the buy/sell/buy trick, i make 300.000gp profit
for a lot of gems just kill the earth troll at greatwoodlake get the xp and rubie, walk out the map, walk back and startd again.
I used oakvale to sell and buy cause that guy has WANTED: RUBY
