Anon_Ymous, you are right, there is the USPS option. But, just as an example, I added 7 rolls of 120 film to the cart, just to reach the $25 minimum order and clicked "calculate shipping". The results were $35 for USPS and $45 for Fedex.
Perhaps it's like you are saying, it's not worth it for small orders...
I'm not saying their shipping costs aren't fair, just that it's not practical for people overseas.
