just tried placing 40 different orders on different armor pieces (lvl35 rare).
gonna see tomorrow if i will get any of those, and later gonna see if i will be able to sell them..
if i would get all 40 items, and sell them for buyout prices that were listed at the time, i would make more than 100% of my total investment (invested ~5g, return would be ~13g).
So yeah, gonna c if it works
Update1: Sucessfully bought 14 items out of 37 that i ordered, now gonna try and sell them
