No use crying over...
There's more insanity in the pricing of milk than there was in the price of gas in the post-Katrina days.
When I go to the grocery store, a gallon of the store-branded 1 percent milk typically costs $3.49 or $3.59 unless there's a sale on, and then usually it's only $.10 or $.20 cents off. Milk is almost always more expensive at the grocery store than it is elsewhere -- it's just that it's convenient to buy it when you're shopping for everything else, so many consumers pay for that convenience.
Next door at the CVS pharmacy the exact same gallon of milk -- a name-brand, but, as it turns out, poured from the exact same location as where the grocery store gets its milk -- is almost always $3.09.
At the Mobil gas station/convenience store up the street from the grocery store, that same name-brand gallon of milk costs $4.49. Meanwhile, if I travel a couple of miles south to a Sunoco station located on the same road, I pay $2.39.
Yeah, I'm familiar with the concept of a loss leader, but that's a big, big delta.
