I also was a big Amazon customer. We have a few of those Alexa devices (all unplugged and stored away), subscribe and save items, the Amazon Unlimited, Washington Post etc. etc. I did pull the plug last Spring but then ended up resigning to Prime month to month for the Prime Video streaming ... then got sucked back in for a few months. Yesterday I cancelled it again. My husband asked me this evening if I pulled the plug and I said yes... then he told me that one of his favorite Prime series was going to start back up. It is one of those that releases an episode weekly so I told him in a few months, after it is finished, we can sign up again for one month and binge it. Also, I discovered that many of their Amazon Originals are released on DVD.
I find deleting the app from your phone and removing the credit card information can slow your roll as far as ordering. You can build a cart and then give yourself time to think about it. Return a week later and see if you still want the items. I ended up ending my subscribe and save and located the original company websites and ordered from them.
As an alternative to the ebooks/books/dvds etc. I have decided to use the library. If there is a book I absolutely want to buy... I try used (Better World Books) or local source (used at thrift stores or local used book stores) or just buy from a local bookstore. My library has ebooks I can borrow via Libby and Hoopla. I live in NYS but about 5 hours from NYC. But because I am a NYS resident and pay state income taxes, I also have access to the NYC Library digital collection. It is just a matter of renewing it when required. I chose The Brooklyn Library as my "home" library in their network. Also, there are local state universities where I can access their collections.
I have decided to jump on the No Buy Train this Christmas season. I will just send money and the recipient can choose what they want for themselves.
