New York Times Article - 99 Cent Pizza Slices

Earlier this week the New York Times ran an interesting article about the proliferation of pizzerias offering $.99 and $1 pizza slices as an affordable meal option.  Loved the article, but had to think that's something we Pittsburghers have been lucky enough to have available for years!  I was just looking through some pizza menus that I have on hand, and saw many that offer slices in the $1 to $1.50 range - Luigi's, Carol of Casey's, Spartan, DiSalla's, Danny's - and that's just naming a few.
