Apple isn't the only company making digital audio players, you know. And opting for a product from another manufacturer can save you big. Case in point: SanDisk's Sansa Clip. The 4GB version of this music player, which is small enough to clip onto a pocket or a sleeve, usually lists for $80. But today, you can find it for as little as $47. That leaves you with plenty of cash left over to fill it with tunes.
