Payment is to be made by Pay Pal. Shipping is through the U.S Postal Service. In the United States any item under 13 ounces will be shipped first class mail, items weighing over that will ship parcel post. I ship world wide, international packages weighing under 4 pounds will ship first class international mail. Over that packages will ship priority international mail. I combine shipping by weight, so please if you are purchasing multiples, ask for an invoice, so that I may do so. Insurance is optional on first class or priority in the United States. In international mail it has to be priority to insure the package. I can't get insurance on first class international mail.Shipping discounts are given on multiples. Due to the updates, some of my ads are not on the sight. If you don't see something, please ask, it is probably in stock. I should have everything updated soon. Thank you for shopping at Kats, I appreciate you business. If you have any questions, please don't hesitate to ask.
