I changed my order to change mailing address (I entered the wrong address in error). Then I called back to change/advance the delivery date. Both times, customer service was exceptional. Also, I really like how a proof was provided to show the color of my image, an explanation of what I was proofing, and lines for the die cut position I desired. The window clings arrived before the estimated time and look just as I imagined. Thanks so much for the outstanding performance.
