so if I pick groceries I would pay 2.75% processing fees and get back 6% if I have the blue cash preferred? Is there anyway for AMEX to tell that you're using square?
lechorah yes. Of course they can tell. Question is if amex can tell you're the merchant. Square will block u if u use ur own card a lot so make an AU.
The bigger question is what happens if u charge $100000, on cc's that give enough points to make it worth 2.75%. I know Sq. Audits accts that charge over 1000/wk... Anyone?
