PrairieDog:
Look at the sole of your new bike shoes. At the ball of your foot, is there a long hexagonal kind of pattern, maybe an outline? (about the size of half a dollar bill) Your bike shop guys can use a knife to cut along that hexagon/rectangle/whatever, and peel off that piece of sole. Under that piece are recievers for cleat-screws. You don't need to buy another pair of shoes for cleats.
