You can redeem your cash rewards as soon as you’d like at any amount, unless you’re redeeming for an eligible Merrill 529 account one-time contribution or a check, which requires at least $25 of cash rewards first. Automatic direct deposit redemptions to a Bank of America or Merrill account also have a $25 cash back minimum.Once you redeem your rewards, you can expect to receive your cash back for purchases in that billing cycle usually within 30 days of that purchase.
