Start with the product itself
Confirm that the page describes a digital audio program and not a different product using similar brainwave language. The supplied artwork is not enough by itself; the product name, seller, and checkout should agree.
Check the money details
Look for the final price, currency, one-time or recurring status, and any optional items. Save a screenshot of the checkout summary. Promotional pages often show a simple number while the actual payment screen contains the operative terms.
Check delivery and support
A digital purchase should explain where the file or access link arrives. Save the order number and support address. If the email does not arrive, check filtered folders before creating a second order.
Set an evidence boundary
Decide what you are buying: an audio routine to try, not a proven treatment. No amount of checkout reassurance can turn a general gamma study into a clinical trial of a consumer recording.
