Here in Orlando, a gallon of milk costs $3.89 or up to $4 if you shop at Publix. A loaf of bread, the generic kind costs you $2, a 16 oz tub of butter costs about $2.50. Iceberg lettuce is at $2 each, 1 pound of the small Roma tomatoes is .99 and 1 pound of Bananas is about .64, basically one banana.
So I think, technically Orlando can be considered the priciest cities, actually more than New York City itself. It has to do more with being a tourist town. Everyone thinks they will benefit from the tourist, so those of us that live here suffer the consequences.
Anyway, if you want to know what I am ranting about check out this article.
