Amazon now has a promotion to subscribe to Amazon Music Unlimited and buy an Echo Dot (3rd Generation) for $0.99.
Offer terms:
This is a limited-time offer of 1 month of the Amazon Music Unlimited Individual Plan for $9.99 ($7.99 for Prime members only) and an Echo Dot for $0.99, for a total of $10.98 ($8.98 for Prime members only). All items must be purchased in one order. Only first-time Amazon Echo device owners are eligible for this promotion. Current Echo device owners and current Amazon Music subscribers are not eligible. After the 1-month promotional period, your Amazon Music subscription will automatically continue at $9.99 per month ($7.99 per month for Prime members), plus taxes where applicable, until you cancel. Offer valid while supplies last.
This offer is only for new Echo Dot users. Prime members can subscribe to Amazon Music Unlimited for $7.99 per month; non-Prime members pay $9.99 per month. This can be stacked with the Chase/BoA Amazon Music offer.
Final order example:
If you are not a Prime member, your order needs to reach at least $25 to qualify for free shipping, otherwise shipping fees apply. For non-Prime users, you may want to try the $0.99 offer for a short period and decide after it ends whether to keep Prime. Likewise, remember to cancel Amazon Music Unlimited on time to avoid an unwanted renewal.
