The limited-time Audible Rewards program could score you $40 in coupons. Every time you spend three credits on Audible, you'll receive a Rewards email offering a $10 coupon for your account. All you need to do is enable "Sales and Offers" notifications through your Audible settings.

Coupons earned through Audible Rewards can go toward any cash purchases (though, unfortunately, you can't use these rewards to pay for an Audible subscription fee). The Audible Rewards FAQ states that you can earn a total of $40 through this promotion, and that coupons will arrive in your inbox within ten days of spending three (or more) credits.

"Audible Rewards is our new rewards program to help level up your listening. For every 3 credits you use, you'll get a $10 reward coupon that will be delivered to you via email ... Eligible customers may receive a maximum of four $10 coupons until the program ends on June 30, 2023."

Along with the $40 you earn by spending credits, Audible may send you "bonus reward challenges" for a chance to win some extra cash. But the company hasn't specified how these bonus challenges work---presumably, they'll pop up in your inbox.

Note that returns are not eligible for Audible Rewards. Additionally, this program requires a subscription to Audible Premium Plus or Audible Silver. Your rewards coupons will expire if they aren't redeemed within two weeks.

Also, this promotion is only available for a limited time---Audible Rewards ends on June 30th, 2023. We're not sure why Audible Rewards is such a short-lived program, but hey, we're just happy to get some coupons.
