Such a great app, I love the clean design, makes it so easy to shop from my phone. The owner of this place is so fantastic.

Good to see MA is keeping up with the times and going mobile! Only bug I am encountering is the location services stays on even when the app is closed. Really drains battery. Other than that it is a good app.
