All books deal several lines on basketball and football full games. I am talking about buying points, in most cases buying a basketball game down from -3.5 -105 to -3 will cost you an extra dime, (-3 -115). The same goes for + 3.5 -105 or -110 to + 4 -115 or -120, depending on the juice offered on the original number by any particular book you choose to play at. Naturally books that offer reduced juice to begin with will charge that much less juice to buy a half point.
