I tried to buy a stem on Amazon recently because I stripped the threads on mine. Found a kind of interesting knock off and figured I'd try it for 14$ shipped Prime. It got sent to the wrong shipping center, and then it showed up as damaged or lost in transit!!
I've always hated Amazon, there's just so much convoluted and wrong about the way their site works, and now they're becoming a global tech superpower like google... no thanks.
