Little Caeser, Pizza Pizza and Dominos are friggin terrible pizzas, holy crap. Having tried those enough times in the past, I don't even bother ordering from there anymore. There are so many way better pizza places. There's one decent cheap place ($15 +tax/tip for a large all-dressed pizza), they use a lot of local ingredients. It's not the best pizza, but for the price it's good and it beats all the other cheap ones that are barely even edible. For $20, there are a lot of options for a good large pizza. Places you go and sit down for a nicer experience you obviously end up paying more, that's to be expected - but even then there are places that make amazing pizza where you can get a perfectly large serving (not a "large pizza", but still more than enough food for one person) for like $12-16.
The value for the aforementioned cheap-ass pizza places just isn't there IMO they are just too ugh for not enough of a savings to bother
