Shipping & Returns

All Cipher 9 books are sold and fulfilled through Amazon. When you purchase a book from a link on this site, you are completing your order on Amazon.

Shipping rates, delivery timelines, taxes, and available shipping methods are determined by Amazon based on your location and selected options at checkout.

After placing an order, you can track your delivery through your Amazon account. Amazon provides shipping confirmation, tracking numbers, and estimated delivery dates directly through their platform.

Returns and refunds are handled by Amazon according to their return policies. If you need to return a book or request a refund, visit your Amazon orders page or contact Amazon customer service directly.

Cipher 9 Publishing does not process returns, refunds, or exchanges directly, as Amazon is the seller and fulfillment partner for all orders.

If you have a question about the content of a book, puzzle difficulty, print quality, or anything related to the product itself, we are happy to help. Visit our contact page or email hello@cipher9.co.
