From where I sit, the out-the-door price is what matters, and I don't particularly care who pays what. If I am thinking about making an offer, I am more likely to put my negotiating "weight" behind the price-per-point rather than that plus ask for closing costs. The one exception might be if the price per point is already attractive relative to the overall market. In that case I might go the other way.
However, I am also not the "get the lowest cost possible" guy, because my time and sanity has value too. I don't want (or need) to spend many hours to save hundreds of dollars.
