I think what you're asking is if the three-way price is better than the two-way price, is there a difference. The answer is no, there is no difference. I don't know why books sometimes list the three-way and -.5 two-way prices differently. Take the best one. For instance, right now I see Corinthians at -.5 -127 and -121 on the three-way. It's the same bet, so take -121.
