Something that made me go: "WTF?"
Today I go to send out some gear. Two identical boxes, same method of shipping, weight is +/- 50 g. One to Florida, one to Hungary. $27 for Florida, $23 for Hungary... Worst thing is that they were given exact dimensions and weight of both boxes over the phone and quoted me $43 for Hungarian package which buyer paid. So now I have to send him some money back via PayPal and cover 4% PP fee...
