If you are only ordering stickers within the U.S., it will give you Standard Shipping ($3.95) or Shipping with insurance ($5.95) options at checkout. Both of these come with a tracking number. If you would like a cheaper ($0.55) shipping option with no tracking, leave me a note at checkout and I will refund you the proper amount after you order.
*However, if you choose any shipping method that isn't insured, Pop Pastel is not responsible for any lost or stolen mail.
