Just in the last year ups and fedex have instituted an additional charge for products over 96 inches (https://www.ups.com/us/en/help-center/sri/glo-lpks.page and https://www.fedex.com/content/dam/fedex/us-united-states/services/Fees_Shipping_Information.pdf). I know that shipping costs will eventually be connected to carriers’ apis, but in the meantime, it would be wonderful if you could allow shipping costs to also allow for length (or dimensions).
