The way prizes are distributed at Magic Premier Events is changing. Starting with Grand Prix Charlotte (June 12-14, 2015), all payouts will be handled by i-Payout. This change will allow payments to be processed more quickly and in the method desired by the recipient (PayPal, check, or wire transfer).
Prize winners will receive notification from i-Payout to their address of record in their Wizards Account. If you are planning on attending a Premier Event, make sure your Wizards account is up to date as it may impact your ability to receive prizes in a timely manner.
