How we verify prices

Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price only. PeptideTech earns a commission when you buy through a link; it never changes the order.
