You'll be saving $70 regardless of which channel package you choose.
Brad's Deals Editor Michael,
New DIRECTV NOW customers can save $70 on the Amazon Fire TV with an Alexa Voice Remote since it will come included at no extra fee when they prepay for one month of DIRECTV NOW. Channel packages start at $35 per month. The lowest price we found for the Fire TV elsewhere was $69.99. This is the latest model of the Fire TV that supports streaming in 4K and HDR and has Alexa built-in to its voice remote. When you combine the Fire TV with DIRECTV NOW, you'll have access to live TV, on-demand programming, and streaming services like Netflix. Additional charges and fees may apply.
