comfortable shoes, that's terrible (but hilarious, lol)! I just dont gamble with shipping from china. I ordered screen protectors from china for the blackberry I used to have back in 2009. They were like $2 for a 3 pack with free airmail. Never got em. And this was on ebay. I emailed the seller and they claimed to resend them. Still never got them. At the time I was new to ebay and did not know I could dispute a transaction. Ever since then, no more free shipping from china for me. When I go to ebay, I set my preferences as Buy It Now, Price plus shipping low to high, item location u.s. only, and 200 results per page. I typically tend also to look for free shipping also, but dont set that as a filter, because I've gotten too few results that way. Anyway, sounds like an interesting little alarm. Maybe zip-tie it to your seat rails, or under your luggage rack if you've got one.
