The Wii has been on the list for at least 2 years. I don't know of any other items. It wouldn't surprise me if the Wii Fit make the list.
1) This thread is over a year old.... 2) The person didn't want to divulge their secret "niche" yet if Amazon wasn't paying them anymore for that niche product, then what did he have to lose? 3) No one else, in the past year, has chimed into the conversation here saying that Amazon did the same thing to them. Obviously, this person was probably doing something shady (ie: bidding on a no-competition keyword for Amazon) or cookie stuffing... got caught... and was told that he wouldn't be paid on those items.
Breakaway: The initial posting was very old as you said. But, at the same time, I don't see why one needs to divulge the niche to discuss the topic here. btw, Your signature links doesn't seem to be working!
