When does the 18,000ki gold pre order bonus end?

What is the deadline for getting the pre order bonus for season 3 ? Is it March 28th or something sooner ? If anyone knows , it would be greatly appreciated. Thanks

The pre-order bonus ends when S3 comes out (March 29th) I believe.

The moment the game is in the Xbox store, I guess the pre-order bonus ends, because then it would no longer be a pre-order.
