Shipping more is usually cheaper, but under certain circumstances it can be more expensive. That's due to the segmentation (shipping brackets) works in the agents' billing model:
- 4000g to USA w/ EMS: $121,64 = $30,41/kg
- 4001g to USA w/ EMS: $133,98 = $33,49
As you can see this one single gram (the weight of a paper clip) costs you $12 in this scenario.
You can use our shipping calculator to verify these results yourself.
It's important to know this, because there's actually something you can do about it?
