is there a reason a storeowner wouldn't have to be out of his or her mind to accept amazon wallet? Amazon already actively cannibalizes sales of merchants on their platform by figuring out what sells best and sourcing their own products to compete. Now a storeowner would be telling amazon who their customers are (particularly their valuable ones) and maybe even leaking what they're buying.

I don't understand why anyone would possibly use this over square, whose ambitions don't include competing directly with the storeowner.
