Sorry, we do not randomly include free stickers if they are not requested. To receive a free sticker you must add it to your cart before placing your order. There is no shipping charge on stickers, even for international orders.
Only one sticker will be shipped per order; your first pick will be included.
If you did order a free sticker but it was not included in your package then our supply has simply run out. We apologize for not updating the store in time! Simply order two free stickers with your next order and both will be included; just make note in the special instructions section stating your previous order was short.
