Cool! Just today I ordered an ace flag patch for my work hoodie, and my black ring from a seller on Amazon arrived yesterday—a great deal for 1¢ + $6.95 S&H. Since they're so cheap I was going to order a range of sizes just to be safe, but alas, they won't let you combine the shipping cost if you order more than one. I recommend trying on rings in a store to find your size; I tried measuring myself using instructions from the web, and I ended up with a ring that's a size or two larger than it needs to be. It's not big enough to be a problem but I am slightly annoyed at myself for not taking a better measurement.
