Problem with seller about shipping charges and ways of payment

I have bought a catalogue for $14.95. I have not seen the little letters where the seller refuses payment through Paypal for international buyers, I just have seen Paypal payments allowed (I always Paypal through Paypal or Billpoint, except for expensive items, there I pay through Bidpay or bank orders). I am in Paris, and don't want to pay for an expensive money order because of $14.95 nor an expensive shipping! As this bought is really a little bought, I asked the seller to accept Paypal and to ship surface mail, without insurance, only with a Certificate of Mailing (total cost: $4.70) and eventually a reasonable handling fee. Sometimes he accepts and asks me a statement, that I will not cancel my Paypal payment, that I assume all risks of an uninsured shipping and that I will not post a negative feedback - I have already made this statement twice, in a direct email to him and through Square Trade -, sometimes he plainly refuses, tries to close the Square Trade case and tells he will make a claim to EBay. His minimum fee for US shipping is $6.50, with insurance and $2.00 handling fee. But insurance is impossible with surface mail to Europe! And I don't need it. I have only very positive feedbacks (more than a hundred)for items mostly bought by US EBay, and don't think it is fair from him to ask me to pay twice or three times the price of the catalogue on money orders and shipping costs. Is there something I can do? Someone can give me an advice? How will EBay react if he makes a claim? Thanks for any help.
