I bought one for $6.
There's a good amount of brownie squares to go around. I would say enough for at least four people unless you're really crazy about dessert. For the same price as Papa John's Mega Chocolate Chip Cookie, the brownie goes a lot further in feeding a crowd of people.
My only nitpick would be there aren't that many chocolate chips to go around. I would say it's a fair amount but doesn't really get into chocolate chip cookie territory.
