Here's the instruction on how to order:
  Browse our library of stickers and magnets. Each sticker and magnet has a number at the beginning.
  Use the link to purchase the sticker or magnet that you want.
  Choose the total quantity that you need, and then "add a note before checkout."
  Write down how many pieces of a particular sticker or magnet you need (just use the sticker or magnet number). For example, if you are buying 30 pieces, you can write in the note section: "Please send 10 of sticker 2558 and 20 of sticker 2412."

  Proceed to checkout.
