Ordering directly from overseas vendors can be a little unsettling if you don't do it often, but I couldn't find the product I wanted from a domestic vendor. Overseas shipping rates change frequently, so it's not uncommon to receive a second invoice for additional shipping charges, especially from smaller businesses. Internet commerce is awash with scams, so when an email arrives requesting more money for something you've already paid for, it's reasonable to wonder if you've gotten yourself involved with something shady! But this company is legitimate: I completed the extra steps to pay the increased shipping fee, and received my product order quickly and in good condition.
