We have an undertone growing in this thread. It attempts to put the onus or unscrupulous label on the seller. Maybe it needs to be on the "good clean buyer" who won't pay full price for the gun and its grips. They feel they can wheel and deal and since they're buying the package, they should get a discount on it.
For whatever reason, they want the seller to pass along that latent profit to them instead of realizing it. The only way to enforce your feelings of ethics is to willingly pay more for a complete package. If you don't or won't, then you're the blame for the split up, not the seller who wants full pop. View it from the other guys side.
In the past I've seen displays where a guy has a nice set of older wood for sale on his table. If the price is right, I'll buy them. He can sell the gun later or maybe its already gone. Usually shooters don't even want the original wood (except to make a full package and enhance their value.)
Just a contrary view of things...
