K1NG's Part:

So there are sales at 26, 26, 27, 31, 33, 42, 48, 49. Sales at 48 and 49 are probably too high due to high minis, sales at 26 quicksold and the one at 27 is kinda bulky.

I would go with 31-42 here.

EDIT: Actually, the 42 sale is wrong. That sale is closer to ~36 keys using classies sellers as minis for the Aussies. Resuggest at 31-36.
