In order, as of patch 7.05:
Sometimes you've got more gold than you have slot space. Maybe getting that S&Y, Desolator, and Bloodstone weren't the "optimal" choices... or were they?
I made up this list to give you an idea of where your slot value is going.
Highest Value with Unique Items and BoT L2:
7720 + 7195 + 6400 + 6200 + 5900 + 3000 (BoT) + 4000 (Shard) = 40,415 gold
As above, without the Rapier:
7720 + 7195 + 6400 + 5800 + 5900 + 3000 (BoT) + 4000 (Shard) = 40,015 gold
