this looks like a case where the seller is trying to avoid paying ebay fees by keeping their final auction amount really low and recouping actual costs through postage....
I've had to do this for some auctions in HK... BIN price = 4.99AUD, Postage = 150AUD...Luckily i have bought from the HK guy before otherwise, insurance and paypal claims if things had gone wrong, would have been a total nightmare to recoup....
Even so, that x-brawn doesnt look like its worth 101USD total anyways...
