As Jake said, certain Casey's stores deliver at certain times of day. Not all stores, not all destinations,not all of the time. The best way I know to check is via Casey's Android application or their website. If those say yes, then you are sure you can get delivery. Even if they say no, you can call a store and ask them if they would deliver to you.
Yes at certain times, certain stores
