Previously, FlipperTools provided a tool for finding the cheapest, best box to ship your items.
Now that USPS Regional Rate boxes have been discontinued and USPS Ground Advantage has been introduced, this tool no longer works.
To find the cheapest way to ship a package today, use the free Reseller Shipping Calculator. It compares USPS Ground Advantage, Priority Mail, cubic, flat rate and Media Mail, or see our other tools.
