Welcome to "Not Living in the United States Shipping Costs"
Out of curiousity, I checked what it would cost to eBay one to Canada - the answer is 32$ for the blaster and another 19$ for shipping. Of course, I can just go buy one in a local shop - for 24$ CAD, so not too far out of line from the USD price in the States - but there's lots of things I can't do that with, and then, well, it gets expensive. And I'm just next door without a pesky ocean in the way!
The US has really efficient, and thus really cheap, internal shipping, making a lot of things way more affordable in America than they are anywhere else. Though on balance, I'd rather have centralised health care.
