Exactly, the key point about good pizza is good quality of ingredients, (and a wood oven, no good pizza is possible with electric oven in my opinion). How many pizza can you eat every month, considering it's full of carbohydrates? Not enough for 0.75, 1.00, or 1.50 to be that different after all. Quality is the first feature one should search in food.
Price, sadly, may not reflect quality of ingredients used. It probably depends on country culture, but at least here you can go to an expensive place and get stale cheese buns. And vice-versa, large networks are in position to sell better quality for lower price due to economic factors. I'd say that having paid more you can't be less alert about what you eat.
That said, I agree with your point (considering that I'm from Russia and you're from Italy, my positions in a pizza argument would be fairly weak anyway =)), my objections mostly apply to grandparent post.
I've always found with a sufficiently large organization if they had the choice between using their clout to purchase cheap but inferior goods or slightly less cheap but better quality goods 90% of the time they choose the former.
Invariably there are exceptions to the rule when competitors want to differentiate themselves. Walmart is cheap quality cheap, Target is better quality cheap.
Acer was trying to get out the cheap computer business and the CEO got fired for it. No one ever gets fired for squeezing a few more cents out of the system.
