How to reach a person.

Last updated 20 September 2026

Email

shopatcipher@gmail.com — this is the fastest way, and it reaches a person rather than a queue. We answer within 2 working days, usually sooner.

What to include

If it is about an order, your payment reference helps but is not essential — the email address you bought with is enough for us to find it.

Refunds and problems

Refund requests, undelivered books and payment problems all go to the same address. See the Refund Policy for what happens next.
