I was just thinking that, since Square charges a flat 2.75% for all cards for all merchants, and Chase Ink earns 5 UR points per dollar spent at office supply stores, what would happen if I started selling pens and notepads out of my garage on the weekends as a hobby and applied for a Square account for my "office supply" business. Would I then be able to MS 5 UR for only 2.75 cents, or would everything code under the general merchant Square code.
