    PDQ shipping , well packaged, as described, good value. Your shipping was very prompt but the postal service did an extremely POOR JOB of getting it to me. It went back and forth between two post offices several times. With the outrageous prices of sending an item they could and should do a better job. I love the sweatshirt and it fits well. Thanks for the bargain and I will keep you as a favorite for sure.
