For $350 you can get a Prime-exclusive Moto X4 and second-gen Echo
(Android Central)

Why not bundle and save? We did recently see the Prime-exclusive Moto X4 drop down to $300, and while this isn`t quite as affordable as that, it`s actually a better offer. Amazon currently sells the phone on its own for $349.99, but for a limited time, you can get a free second-gen Amazon Echo with the purchase as part of a bundle. The Echo sells for $99.99 right now. You can pick between the silver and black phone for the bundle, but it doesn`t appear as though Amazon is offering color options for the Echo itself. Experience the true capabilities of Alexa using its hands-free on both the Moto X4 and 2nd-gen Echo. Use it to control your smart home accessories, answer your trivia questions, listen to music, and so much more. See at Amazon ...
