Amazon.com and Audible announced a $100 instant rebate on Audible-ready portable audio players and PDAs for buyers willing to join Audible's AudibleListener program for 12 months.

The AudibleListener programs are monthly subscriptions that allow customers to choose two programs from Audible's collection of spoken word audio programming for a discounted price. If you select BasicListener, you can choose one audio magazine, newspaper, or radio program, plus one audiobook, each month for $14.95. The PremiumListener program costs $19.95 per month and allows you to choose two audiobooks.

If you are in the habit of listening to audiobooks while travelling or exercising, this is an excellent deal. Next time you are in a Borders or Barnes & Noble, take a look at the cost of audiobooks on cassette or CD, then compare it to the regular price charged by Audible for the same program, and you'll see that already there is a considerable savings.

The AudibleListener programs commit you to purchase programming on a set schedule, but, you may already be purchasing audiobooks at a rate of one or two a month anyway. If that's the case, joining this program will reduce your costs and you'll get a $100 discount on a new high capacity audio player like an iPod or an iPod mini in the bargain.
