I saw an offer earlier, but when I went to the home page, it wasn't there. Where did the offer go?

The offer either expired or was redeemed. Expired offers can be accessed on the rewards summary page in Online Banking. The expired offers page shows your expired offers in the last 90 days.  Redeemed offers (for the current month and previous two months) are also displayed on the rewards summary page in Online Banking and in the Mobile Banking app.
