Once you click the button there is no way to stop the order. None. It happened to me after I realized I had ordered the wrong color, and when I immediately called them on the phone I got a message saying that my order had already been shipped, in what, like 5 minutes? There was no way for me to deal with these people. Don't order from them. They are scammers. And by the way, the famous Wintersilk long johns and T shirts shrink making them unwearable. They crawl up to your calves and knees!
