You just never know where this flip journey is going to take you.

After months of cranking out CollX wins, it has been COMC with the most recent “bigger” sales successes.

That’s a good thing!

Diversification is a great tool to have when sports, platforms, and methods get a bit slow.

Yesterday the focus was on saved searches, forcing sales by sending cards to auction, and comping with your gut “feel.”

Today is something different with a little of the same, and a bigger result.
