Affiliate disclosure
Amazon Associates statement
As an Amazon Associate, Sleep Pathways Guild may earn from qualifying purchases at no additional cost to the purchaser.
Amazon links used by the Guild may include the tracking ID spg_rpsgt-20.
How affiliate links are used
Affiliate links may appear in the optional bookstore or resource shelf when a book or study reference is relevant to sleep-technology education. A purchase is never required to use the free CPSGT app, RPSGT app, EKG learning tools, articles, downloads, or other public Guild resources.
Editorial independence
Affiliate relationships do not determine educational conclusions, question content, source selection, or whether a resource is included. The Guild may also link to official organizations, publishers, and non-affiliate resources when those links better serve the learner.
Product information
Prices, editions, formats, sellers, and availability can change. Learners should verify the title, author, edition, ISBN, seller, and current product details before ordering. Sleep Pathways Guild does not control Amazon listings or third-party inventory.
Link labeling
Affiliate links are disclosed near the relevant collection and may use sponsored and nofollow relationship attributes. Non-affiliate official resources are identified separately where practical.
Questions about a link or disclosure may be sent through the contact page.
