hey i would like to share this i cannot try this because i do not ave a good player yet, so here goes,
first get a lvl 90+ can 1 hit lvl 1-30 preferable then go to twin city with partner or with multi client and kill lowbies that are made to sit in market all day with your main and once killed them get your friend or other client and pick up the mets and everything. But make sure that when you see someone near warehouse getting stuff wait until they move so that they got inventory full or wateva.
make sure that they are going to market, look at name. example would be "met shop" "+1 shop" and other easy to guesse names that will be going.
