Kinda new to posting, but I found out something that might come in useful gearing up alts.
Since a few patches you are able to send 'Battle.net account bound' items to your opposit faction alts. So I decided it was time to reroll horde and bought a load of heirlooms to send to him.
Now the exploit kicks in:
When you send a justice reward (I.E. Tattered Dreadmist Robe) to a character of the opposing faction, it will reset the 2hr refund function!
Tried this and had a lvl 5ish mage with justicecap. Not 100% sure about honor yet, but I supose it works the same (sorry for the theorycraft on honor :P)
EDIT: If you want the justice on a same-faction alt: buy > send to other faction > sell > buy new > send to alt on original faction
Hope it's useful for anyone
