All sales are final. Some items are limited edition, and some are print-on-demand, so we cannot offer exchanges or refunds. Please be sure to click on the item description for details and add the correct shipping address at checkout. We are not responsible for lost mail from the mailing system. We offer a route insurance fee for your order at checkout (at only 0.98 cents) and I encourage this at all times. If you still have questions, feel free to reach out to Laura at cosmicmedium@gmail.com.
