This is the email message I recieved from Amazon.com after one of my orders didn't come on time. (I didn't even care. I didn't contact them or ask for anything.)
"We’ve refunded any shipping charges associated with your shipment. We’d also like to provide you with a $20 gift card to compensate for this inconvenience. This amount will be applied to your next eligible order automatically without entering a claim code. Amazon.com Gift Cards can be used to buy almost any item sold on Amazon.com."Now this is customer service . . . and it wasn't even their fault! Thanks Amazon for GREAT service!!!
