Ask him to use USPS. I get a rate of $90.20 for insured USPS Priority Mail to The Netherlands. Shipping calculator is located link
Assumptions: 20 lbs packed (8.1 kg unpacked according to Beoworld). Box size: 24"x18"x8". Insured amount: $125
The UPS shipping calculator is link. It requires you input your postal code.
Thanks Mediabobny🤒
Seller respond on my mail and lowered his shipping price to 125$ because he does not want to lose money on this transaction. Now let's see what he says with the USPS shipping calculator as you suggested. I don't mind paying this amount but you can not charge more then the actual costs for shipping.
There are two things that everybody forgets to add to the cost of shipping.
The first is the cost to the seller of the box and packaging. This must be passed on to the buyer as an addition to the "actual shipping cost".
The same goes for the cost of taking the item to the mail, when a service like USPS is used. This can be significant where the journey is a significant distance (don't forget the cost of return journey!) and then there is the cost of parking!
These are both part of the "actual shipping cost" and they are not included in the USPS shipping calculator described above.
