28k but you have to grind other 2k. +keep in mind that you have to have Mythic box in slot to complete last quest, which is painful enough to find...
I get used to save epic/legendary/mythic box when I fight in tower. So when the pussy market start I usually have some of them.
yeah, I use the same tactic, but thing is that Mythic box spawns is about once in 2 weeks (at least for me).
