Observed provider quotes. Blank cells mean no valid capture at that checkpoint, or a promotional price we decline to publish; they are never interpolated. A discount is not a rate, so a promotional price is dropped rather than shown — neither as the headline figure, which would understate what the route durably costs, nor as its struck-through list price, which would overstate what a customer pays today. Final warehouse measurements, dimensional weight, promotions, services, duties, and route availability can change the checkout total. Full table and methodology on the scoreboard.
