UI is constantly changing, leading to a disjointed experience with the app. "Orders" page is constantly buggy, often not loading. Several times I have had delivery personel deliver packages by throwing it at my door... never enough packaging in the boxes, and sometimes the thin paper tape is torn or not put on properly to seal the box. Returns are confusing, and they make you drive to a Whole Foods or a participating UPS store to make a return when they screw something up... highly frustrating.
