Well here is an option for you. Find a coupon and you can have Dominicks make the pizza's. Normally their large pizzas are 16" and about $10. However, on fridays the pizzas are only $5 each with a perferred card. You can find coupons that bring it to $7 each on normal days.

Their pizza's are pretty good to. We end up buying pizza every sunday at the bash at the end. Or we go out somewhere for dinner. The 2 pizzas we get usually feeds about 4 to 5 adults. So the normal price for 15 people would be near $65, however if you get the coupons its going to be about $42 if you get the $7/pizza deal. In addition to that you can get a 10% discount for preferred members as well.

Just a thought for you guys who want to do this.
