Going with an overseas source is usually cheaper, especially if you test the product or find a group to split testing costs with you. Some just don't like the risks. And yeah, bfflist and some others are among the cheapest in the US. Lots of overseas sources have US warehouses. A little research can save you a lot. I did 2 months of research before buying anything. I'll help people who put in effort, but I'm not gonna do all the work for them.
