A week ago Amazon listed 11,000 "Confederate flag" items online at its Canadian store. This dropped to 6,500 by mid-week -- but then the cleanup stalled for a day or so, eventually dropping to 2,500 items a couple of days ago.
As of Saturday they seem to have stopped the purge (although they did put a Canadian flag at the top of the search result).
Previous "stalls" on this cleanup seemed to get addressed when there was public criticism from people like Kossaks and complaints on web sites like Daily Kos.
