the way to vend is look for items that are unsually really expensive (as according to their graphs) and look for one thats a little less
::say theres a midsummer swirl for 35k your browsing around and find one for 33k buy that one. sell it for 34500 you will have made a 1500 profit if you keep this up you could actually make alot of money! i just made 241k off doing that
SideNote:: dont go for an item RIGHT away, try and see if the item will go down a little first.
