We live on a rural island but can get to the mainland by boat and get to a Walmart. So if I go there I'll find a way with bluebird (is that something from customer service department ... sorry I'm a newbie) to use one of my credit cards to buy a money order or check to pay this contractor (and other local businesses like well systems etc) what I owe them in a cash type form they will accept, as a check,is that right?
