It's not really a "rich" to disregard grocery prices. I mean, they are what they are. And in your average American supermarket the prices don't vary THAT much so fretting all day over which bottle of juice is 20 cents cheaper probably is just not worth it. Better to grab the stuff you like and pay up - still gonna be cheaper than going out to even a modest restaurant.
I mean, since I've been back in school I do find myself looking at prices and getting the cheapest versions of staples for which the quality doens't vary that much - eggs, milk, butter, etc. I can notice a small difference between the more expensive ones but not enough to justify the price - my food is still perfectly delicious without fancy butter or whatever. Better to spend it on good bread, cheese, red meat, seafood, beer or wine - most of which a lot grocery stores don't even have anyway.
