Comp. Value
Our “Comparable Value” (Comp. Value) prices are based on the prices charged by Trek or other retailers, in-store or online, for the same or similar items. In most cases, this is a price at which Trek has offered the item for sale, and also the MSRP we provide to third-party resellers based on the prices of competing items in the market.
