What you get: Ranks step-ups by marginal dollars per unit of “value”, flags odd pricing patterns, and highlights one tier as a heuristic “best incremental deal” so each dollar spent can go further.
Shipping speed vs price: List each quoted service on its own row with your estimated transit days and price. Order rows slowest at the top to fastest at the bottom (e.g. Ground → express). Days are your guess (business or calendar)—not live carrier data.

Where to put what: Name (e.g. carrier + service), transit days as a positive number, price for that service. Any order is fine—rows are sorted slowest → fastest for you. Marginal column is extra $ per estimated day saved on each upgrade step.
