The Mama Lucia chain has a Tuesday night pizza special--order one (16" carryout only) and get the second one for $.99. The pizza is decent, and if you have to feed a group of 6 or so its a fairly good deal.
Price for a pie (16") with three toppings is $20, so two come to $20.99.
The crust actually isn't bad. Not too thick, crisp exterior, and soft interior with some yeastiness.
