Last year I ordered a portable bath spa from Shop4 (NW WP partner) and a week after receiving the unit I received a second unit that was never billed (about $50). I decided to wait a few weeks to see if the charge would hit my credit card. It did not. Then I called Shop4 to see if they had a record of the second unit being shipped and they did not. Shop4 buys merchandise from third party suppliers and items are ship direct from the supplier's warehouse. Called Shop4 again and had them send FedEx by the house to pick up the item. I know I would have felt guilty about keeping the spa I had not paid for. Must be that "do unto others..." thing my parents drilled into me. It was also a great lesson for our kids. Anyway. it was the right decision for me. As in past moral dilemma type posts, if you are asking the "should I, or shouldn't I" question, then you probably already know the answer that's right for you. More importantly, just think of the FF miles you'll miss out on if your card never gets charged!
