LightInTheBox offers this Creative Cat Wall Sticker for 48 cents plus 73 cents for shipping. (Shipping includes a 50-cent small order processing fee.) That's a low by $2 and the best price we could find. It's repositionable and washable.
Note: This item ships from China and may take two to five weeks to arrive. Uncheck "Add Shipping Insurance to your order" during checkout to remove the 99-cent fee.
