At Digikey search on iCE40.  That will give you a listing of all the 
parts.  Looks like Digikey's prices are a little high, not just because 
they are Digikey.  The $3 figure I gave is from quotes I got from 
Silicon Blue before they were traded through Digikey.  Like I said, you 
need to get a quote on any FPGA to find the "real" price.

I don't think it is all about the "haggle".  I think no small part is 
about doing what it takes to get the design in and deny the competition. 
  When you get quotes from Digikey web site they never even know you are 
looking at their parts.  Think of it as a live auction vs. sealed bids. 
  They prefer to be in the live auction.
