Purchase notes.

What format will I receive?

Every product is a digital PDF. The bundle contains three PDFs. No physical item is shipped.

Does the flagship already contain the toolkit?

Yes. The flagship includes the twelve worksheets. The standalone toolkit is a separate print-ready workbook for buyers who only need the procedures. The bundle includes it for convenience and clearly discloses the overlap.

How does payment work?

Each purchase button opens a Stripe-hosted checkout. The public page does not collect or store card data.

How are the files delivered?

Your fulfillment workflow must send the correct private PDF or PDFs to the email used at checkout after Stripe confirms payment. The HTML page itself does not securely deliver paid files.

Is this financial advice?

No. The products are educational and do not provide individualized financial, legal, tax, investment, medical, or mental-health advice. They do not promise improved returns.
