I've been buying a lot from Japan lately. Mostly through AmiAmi. Have never paid a single customs fee, since shopping with them from June 2010. I've had items arrived with $50 to $300 valued on the box. Yesterday I had an item arrive from HLJ, and got smacked with a $35 custom fee.

It seems I have luck with AmiAmi. I know others who have been charged customs here, locally, who ordered with AmiAmi. Weird.
