Found the iPhone SE 32GB still available on AT&T Prepaid for $50 with the purchase of at least $30 worth of airtime. The phone does not come included with any account credit (like the $45 account credit that is indicated for an online purchase). Taxes, if applicable, are on the $50.
After initially loading $30 (that is good for 30 days of unlimited talk, text and 1GB data with autopay), you are free to cancel or change to any other plan.
