Merchant Exploit : GW Submissions

The price a merchant quotes you is locked in until you close the window. To exploit you want to lock in a high sell price during a high traffic time, or a low buy price during a low traffic time. Then go to bed or work and wait for the server population to change. If you timed it right you'll come back to find a buy quote below the market sell price, or a sell price above the market buy price. Either get some quick turnaround from buying/reselling to the merchant, or spam the trade channel to get even more plat.

well known, sorry
