I ordered an item June 30th. I paid for one day shipping (granted it was cheap shipping – but that’s not my fault). Amazon shipped the item on July 1st. But somehow mysteriously Amazon can ship out July 1st, promise one day shipping and deliver July 3rd. I am not a PHD in Math — but I am pretty sure that shipment on July 1st with one day shipping should get me delivery by the 2nd. Since when is 1+1=3? Why over promise and under deliver? Or if they need to why not charge me more for one day shipping? I chose to order from Amazon because they could deliver when I needed it. How difficult is it to deliver to a customer what you sold them? I was sold one day shipping. what I am getting is 2 day shipping. To me that is a big difference.
As much as you can as a business owner keep these things in mind. It is EASY to provide good service. Just treat a customer they way you would like to be treated. Under promise. Over deliver. There you see how easy that is?
