In order to withdraw your cash back earnings, you must link a "money out" or withdrawal method, verify your email, and reach the minimum $26 lifetime cashback. Once you have completed all of these steps, you’ll be able to initiate a withdrawal.
You must hit a $26 lifetime cashback balance before you are able to withdraw. The $26 is composed your own personal cashbacks plus your network cashbacks. This is a one time requirement. Once you've earned $26, you can withdraw any amount* any time moving forward.
Keep note that refunds to your cashback balance does not count to the $26.
*for withdrawals through a visa prepaid card, a minimum amount may apply.
