We answer every message from a single support channel, so you always know who you are talking to.

Help with access and delivery

Access instructions for educational products are sent to the email address used at checkout after payment confirmation, normally immediately. If the message has not arrived, check your inbox, spam folder and promotions folder, and confirm the email address typed at checkout. If it still has not arrived, write to us and we will resend the access instructions.

Help with payment

All prices are in US dollars (USD) and every purchase is a single one-time payment, with no subscription and no recurring charge. If you see a charge you do not recognise, contact us before opening a bank dispute and we will identify the transaction.

Help with refunds

You may request a refund within 7 calendar days after payment confirmation. Use the subject line Refund Request — Order #XXXX and include your full name, purchase email, product name and order number. Full details are in our Refund Policy.

Help with Express Tracking

Express Tracking is a priority monitoring and customer-support service for eligible orders that include a valid tracking method. Support can organise and explain the tracking information published by the applicable carrier and help you report an eligible issue. The service does not control the carrier, customs authorities or postal services, and does not guarantee an earlier delivery date.
