Cheapest phone for ibotta

Hello, I'm looking for the cheapest phone for ibotta. The main requirement of this app is that the phone has autofocus which pretty much disqualifies most value phones. The cheapest phone I could find that had autofocus was the Moto E 2nd gen. I'm looking for the cheapest phone which can do close up autofocus shots so I can take pics of the receipt. Without the autofocus the receipt just comes out all blurry and not legible. I figured this would be the right place to ask since ibotta is a good tool to have for beermoney users.
