Amazon has the Echo Auto with 6 months of Music Unlimited for just $14.99. This price matches the lowest price the Echo Auto has ever been, which is 70% off the regular price of $49.99, even when you don’t factor in the included music subscription. Multiple Echo devices are offering 6 months of Music Unlimited, but the Echo Auto is the least expensive one. The 3rd-gen Echo Dot at $19.99 is the second least expensive. Amazon Music Unlimited normally costs $7.99 per month, which is how the $97.93 list price of this deal is calculated. However, Amazon is currently offering Prime members 4 months free without purchasing anything, so you’re really getting just 2 extra months for free when you buy the Echo Auto. The music offer is only for new subscribers. Everyone else can get the Echo Auto for $14.99 without any extras.
