whats the sweet spot so people will bite and the business is still sustainable?

I go to whole foods and get oatmeal somedays that thats 2.50 or abouts

most days I grab a yogurt parfait and thats 3.30

a breakfast meal at mcdonalds is about 6 dollars. (breakfast sandwich, hasbrown, drink)

I'm trying to understand the price aversion not from you exactly but generally
