Looking to enhance your music library? And it won't cost you a penny.

For a limited time, Amazon is offering three months of Amazon Music Unlimited for free. (This offer is only available to new subscribers.) Previously, Amazon offered only one month for free. However, this campaign saves three months, or $19.98. (You can cancel at any time after the three months are up.)

Amazon Music offers unlimited access to a library of 50 million songs with no ads or skip limits, plus it works perfectly with Alexa-powered smart home products like the Echo Dot and Echo Show 8.

There are a few important conditions to note. First of all, this is a new subscriber-only deal. Additionally, if you wish to continue the service, you will be charged $9.99/month after the trial period. (Prime members pay $7.99/month).

Throughout the week, Tom's Guide will be featuring the best sales in July as part of our Summer Savings Event. Check back often for the best deals.
