Naturally the weather is owning Kentucky right now, which is the Amazon hub for Columbus residents like myself. As a result, their shipments have been quite delayed. I opened a chat line about this and was quickly offered free 1 day shipping on another free order. Even better, I explained that I wished to place my own order to make sure the BP referral went through. He was happy to adjust the shipping price of my new order to be free to help BP out (ok, he didn't know who the referral was, but I'm sure he would have been on board).
Amazon customer service is consistently very pleasant and helpful. Kudos.
