Buyer checklist
- Use a current purchase route rather than an old screenshot.
- Confirm the exact bottle count and final checkout amount.
- Save the ClickBank invoice and order number.
- Read shipping and refund policies before paying.
- Keep in mind that active seller funnels may show different promotions.
Why this site separates facts from promotions
Vendor pages are primary sources for the seller’s current offer and policies, but promotional statements are not independent scientific evidence. This site therefore labels current offer information as vendor-reported and uses scientific sources separately for ingredient and sleep education.
