Don't have Prime anymore. When I did have it I never found anything to buy.
As for the Dot I think I will ask $30 bucks for it. Don't need an alarm Don't work so I sleep when I want get up when I feel I can.
Never had any luck getting the Google Play app store to work on my Fire 10... Only app I wanted is the VUDU app. I get the dang thing on all My Movies & just as I want to watch a movie the dang app wouldn't work.... 1st time it Deleted ALL of my Movies I just put on it ...took Months to Download them! 2nd time I got 1/2 way thru a Movie & Freeze! There has not been a 3rd time as I spent $50 bucks in a Insignia Tablet! $10 bucks on a Insignia Speakers.... Now No problems in 6 months
Funny thing is the Insignia Tablet doent handle the Amazon apps... so I only put Amazon movies on Fire & Vudu movies on the Insignia.
