Third party sellers with a "real" looking name will list an item at a ridiculous discount off retail. If you buy it, you get a Chinese international tracking number. This takes forever to "arrive" and it turns out Amazon only really cares that the tracking number shows to Canada. I'm not sure what is actually in the package, since it's not possible to figure out more than just the city it went to.
Eventually, Amazon will refund you, but it's a bit annoying. It's pretty easy to spot once you get bit the first time, but you'll usually see the third party seller spike to several hundred bad reviews before the entire situation gets resolved.
This seems like Amazon CSR just failed to read the writer's complaints correctly. It should eventually get fixed, because it often does get fixed, even for hundreds of customers at a time.
