At time of this writing using Amazon Prime, Movies, Music, Pantry, Fresh, and Kindle. Cancelled cable provider, internet connection, and a Roku. Amazon Movies/TV has the Showtime, HBO, and so on but I prefer to own the movies and like the pre-order option. Internet connection, a Roku or Amazon Firebox with a 4K TV beats a loud and crowded theatre - IMO. Prime Pantry - fill a large box with discounted items such as toilet paper, paper towels, detergent, soap, cereal, to protein bars. Delivered in 2 days, 15% discount off. Switched payment option to Amazon Card with 5% kick back on all purchases. Amazon Fresh for dinner or lunch, goodbye Grocery Stores and entering my phone number to get a dollar off an item overpriced by 3 dollars, save 4 dollars on Amazon Pantry, 15% off the entire order, paid with my Amazon Card, 5% kick back further reduce my cost. If you prefer clipping coupons, they have those too. Just click a button, 1 dollar off an item 4 dollars more at the local Grocery store, I've heard there is more but this is as far as I've gotten. Hope this helps.
