I feel you...I get lazy, too. Shit, sometimes I just wanna play video games and drink beer...lol. I ordered RT a couple months ago and it cost me $27. Since then, I just go to Little Ceaser's if I want pizza but feel lazy. Or, like you said, Costco pizza is BOMB! As far as taste, it depends on who these companies order from. There are a few sauce companies, and I'm sure each of these chains has their own recipes to follow. Another thing is the water...shitty water makes for shitty pizza.
Fast food chains like McD's are a whole different ball game. Prices are ridiculous and the shit is BAD. But, like you stated, they can get away with it because we get lazy. The thing about burger joints is their prices are fairly competitive with each other. Now if it's between a Big Mac or a $6 Burger...I'll be at Carl's because it's in the same ballpark and the taste is right.
Round Table just failed to meet with all the other companies to maintain a competitive edge. Had they offered the $10 deals 2 years ago, they'd be in a different situation. Cats are not spending like before, so they either make it at home or go wherever is cheapest.
All I know is a lot of these places could step their game up and still offer fairly inexpensive products. If the sauce is off, the base was off...they can change the base. If the dough is off, they might want to get better water filters or have water shipped from other areas. Beef, chicken, pepperoni, etc...can all be worked out when bought in bulk.
I like RT, but they're nuts. lol.
