Actually, Wal-Mart sells quite a bit on Amazon. I've bought several items which came in Wal-Mart boxes. Makes sense, Amazon's website is a lot easier to use than Wal-Mart's.
We're Prime members and use it constantly. Where we live traffic ranges from so-so to hideous. We live in a major metropolitan area but locations are spread out over a wide area. Even though retired, I have better things to do than travel to four or five different stores trying to get everything on my shopping list.
Amazon is just one of the delivery-to-your-doorstep services we use. Our public libraries are a disgrace; it's almost impossible to get any good books from them, let alone e-books. When we want a book we want it yesterday, LOL. Some of the library e-books have waiting lists for titles that are literally dozens of names long - and each person can keep the e-book 2 mos. Many don't get returned at all, so the library has to purchase another e-copy to lend out.
Plus, we were using a Barnes & Noble sponsored charge card for several years. We ended up with over $4K of free gift cards from bonus pts during that time - we put most of our daily expenses on a card and pay it off every month. Those cards bought us a lot of books! But we have switched about 80% to e-books now. Most of what we buy from Amazon is drugstore or specialty items.
The e-books I've been buying are through the BookBub service, which allows you to select different genre and receive an e-newsletter listing publishers' special discount prices on books. Many series, for example, will have the first few books put out in e-book form at reduced prices or even free, to try and hook you on a new (to you) series. Because many of these discounts only last a certain amount of time, it's easy to miss them. A lot of them are only worth reading once and deleting, but I have found at least a dozen or so authors I would never have found without the BB service. It works with all types of e-readers, not just Kindle: you set the type of e-reader you have, and the newsletter gives the link to each book that's for sale.
We are eligible for both video and audio streaming, but we don't use them much. Spouse prefers Netflix and downloads what he wants to see. I'm not as hooked on TV so don't watch as much as he does. What I do like is the cloud back-up. Much easier to use than Google's although sorting is best done BEFORE uploading. Prime members currently get unlimited back-up storage.
We recently upgraded two of our computers to Win10 and used Amazon Cloud for back up before taking them into the shop we use. Easy-peasy peace of mind, worked great.
