Update #2: The Echo Dot in Charcoal is currently unavailable, meaning this offer is expired for the time being. This deal may still be live once it comes back in stock.

Update: This offer is back for a limited time! The offer page may not specify, but signing up for this three-month trial for $0.99 will enable a $49 promo credit on your account, bringing the Echo Dot's price down to only $1. Be sure to enter promo code DOT1 before clicking the yellow 'Join Now' button! That brings your total cost to only $1.99 for this offer. Only the Charcoal-colored speaker is eligible for this discount.

Amazon is giving customers the perfect excuse to sign up for its Music Unlimited streaming service. Right now, you can get the newest Echo Dot smart speaker for only $1 when you signup for a new Individual or Family Music Unlimited plan at $7.99 or $14.99 monthly, respectively, when using promo code DOT1. That means you could snag a month of Music Unlimited and the Echo Dot speaker for as low as $9 total. If you don't have a Prime membership, the Individual service is priced a bit higher at $9.99 monthly.

To make this offer valid on your account, there are a few simple steps you'll need to complete:

Visit the following page, click 'Get Started', enter your address and payment info, then enter promo code DOT1 on the 'Join Now' page below the yellow button.
Start your Amazon Music Unlimited membership; both Individual and Family plans are eligible for this deal.
Check your email for a message from Amazon stating a promotional credit of $48.99 has been added to your account.
Add the Echo Dot (3rd Generation) to your cart. (Charcoal only)
View your final total at checkout to ensure the credit has been applied. If not, it may take up to 48 hours after your Music Unlimited signup.

The Echo Dot speaker regularly sells for $50, which makes this a pretty stellar deal. However, this offer is only valid for new users of the Music Unlimited service.

Once the speaker arrives at your home, you'll be able to ask Alexa to play your favorite songs and stream them directly from Music Unlimited with your membership. If you decide you don't like Music Unlimited or don't use it enough, you can cancel your membership whenever you'd like and keep the Echo Dot as a reminder of what you're missing out on. It's capable of much more, too.
