differential precipitation of PCR

Anyone out there familiar with a protocol for the 
differential precipitation of PCR product from primers?  
By this I mean are there certain EtOH/salt/temp 
conditions in which large, double-stranded DNA 
fragments (the product) precipitate but small, single 
stranded fragments (the primers) do not precipitate?  
This would be cheaper and, I think, faster than gel 
and/or Wizard preps.
