The big red X marks the spot for savings! And what a bargain it is. Where else in this great country of ours can you get a doorstop of a newspaper for half a buck? It used to cost 75 cents, but in a transparent effort to stanch the circulation loss north of the Miami-Dade County line, the mighty Herald can now be had for a song. Don't read it? You're not alone. But the price is very right -- the Dade edition costs a buck! So buy an issue or two and use them to line your birdcage, train your puppy, or make lots of those cool hats newspaper printers used to wear while tending to the giant presses.
