I've been charged (or rather my insurance was) $42 for two slices of white bread, a slice of turkey, and 12 ounces of skim milk. Prices are outrageously padded everywhere. It really boils my blood that I can take my dog to a vet and get a procedure done or procure drugs that would cost one or sometimes two orders of magnitude more if I was the one getting work done. I'm half tempted to dress up like Goofy and see if they'll be fooled...
