Yes, Scotiabank too.
The company that is/has placed ATM's in OXXO is Allpoint. They are known for their fee free ATM's in several countries.
Unfortunately, at the moment, they are having an issue with their system in Mexico, and although it will go back up, they are not saying when, nor are they currently listing their machines as being in Mexico. Capital 360 is one of obviously several banks that was offering the use of Allpoint with no fee, and will be again when the system is restored.
