The letter comes from fixed score bands, never a curve. The score can change when this vendor's own records change: a new or older certificate, a change in a listed base price (value points), the number of reports on file, or a new Trustpilot rating (the reputation adjustment). Discount codes never change it. The rank compares the same score with the other active vendors PeptideAudits tracks and never changes the letter.
