Observed provider quotes, excluding promotional prices. Where a calculator displays a listed total beside a coupon or discount, this comparison uses the captured listed total, which may be higher than the price a customer pays today. This is not a comparison of discounted checkout totals. Blank cells mean no publishable capture at that checkpoint; they are never interpolated. Final warehouse measurements, dimensional weight, promotions, services, duties, and route availability can change the checkout total. Full table and methodology on the scoreboard.
