Book, purchase, and download
For anything about We’ve All Become Prompt Engineers: payment, a download link that did not arrive, opening the files on your device, refunds, receipts, and invoices.
When you write about an order, include the email address you used at checkout — it lets us find your purchase without asking twice.
Journal
