Questions
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, except that the labelled featured partner, LA Peptides, is pinned first; “Cheapest” always marks the lowest price. PeptideTech earns a commission when you buy through a link.
