How to get the most out of it: Try to see where the curve startens to flatten. This is the optimal shipping weight where you're taking home most of the savings while still getting the safest shipping. Adding more weight disproportionaly increases the risk of customs, going lower means you're not using economies of scale.

This is not meant as a precise price calculation tool, fees are not included. This does not hinder it in its intended purpose, as the graphs with and without fees are proportional.
