Would an alignment fix this?

I'm looking into purchasing a 1994 prelude that runs and everything but he says the rear tires toe-out a little.All of the rear suspension arms and cross brace with parts from a straight Prelude were put in and it still toes out. My question is if i brought it to a shop and got a 4 wheel alignment would that include correcting the rear tires toeing out? If not does anyone have a rough guesstimate as to how much correcting the rear alignment would run me? Thanks in advance
