90s, eh? You whippersnapper. :p
I remember when the book it program first began back in the 80s. In fact, those personal pan pizzas were my first "real" pizzas and first experience with mozerella cheese. While I had had pizza for as far back as I can remember, prior to that it had always been the pizza kits, which just made a very very thin crust and only came with parmessan cheese.
I'm on the fence about this offer though. On one hand the pizza is good & it would be nostalgic. On the other hand, those personal pan pizzas are tiny, they didn't even fill me when I was 8yrs old. I think this offer would be good if/when I'm already going to pizza hut to get something else, but not worth a special trip just for it.
