Marketplace shipping cost guides

16 oz package with Use a 1 lb package weight, add mailer cost, then compare seller-paid shipping against buyer-paid shipping before sending offers.

Use that as the shipping floor, then rerun the marketplace fee calculator with the real buyer-paid shipping charge, seller-paid label cost, item cost, and offer price so shipping is not treated as free margin.
