Earlier this year, Pinnacle increased their withdrawal fee from 3% to 10% if you do not complete a 3x rollover on all deposits. Their terms now state (Section 7.3):
Take these restrictions/fees into account when choosing what site to make bets on in the future!
Any deposit made to an account which is not rolled over (risked) at least three times will incur, at company discretion, whichever is greater from a 10% processing fee or USD 20 (or other currency equivalent) and any applicable withdrawal fee on the withdrawal amount. Please note that we reserve the right at our discretion to charge fees or a fee in the event of irregular transaction behavior. We also require at least a one-time rollover of any deposit (a deposit risked at least one time) and may reject withdrawals if this was not completed. You are responsible for your own bank charges that you may incur due to depositing funds with us. Exceptions to this rule are outlined in our "Payment Options" pages.
