We seem to be arguing this from such different points of view that we will never see eye to eye.
In order to agree with you I would have to set my mind that its fair for a seller to choose to charge $43 in deliberately over priced Express shipping for a tiny item the size of my pinky toe at a fraction of the weight when he also has the choice to charge $12-$15 In priority shipping and $7-$12 (or less) First class with decent packaging. Let's not get into why local US buyers happen to get free shipping.
Yes the choice does indeed exist since some succesful and long lasting US sellers do provide it regardless of Paypal fees and that's why they are in my favorite list.
We will not see eye to eye on this and I have my own experiences that form my bias and you have yours.
Thank you.
