TLDR: quit Prime, you don't need it and it's probably not even worth it.
I quit Amazon Prime a month ago (after having it for over a decade) due to Bezos/Amazon's actions regarding this administration/WaPo/in general.
I haven't missed Prime at all. I easily find local or niche online stores to buy things. A lot of them have free shipping, too.
Even if your concern is just having it for something like Christmas or an upcoming event- you can just subscribe to Prime later for the single month you need it, then cancel again. You don't need to be paying them so much every year.
If you consider the high price of an annual membership, it might not even make financial sense to keep using it. I actually had to buy something on Amazon after canceling, and once I passed a certain $ threshold the shipping was free anyways, without Prime.
You may have it stuck in your head that Amazon Prime is some essential membership, something you must always have. It's not. Vast majority of you reading this could go and unsubscribe right now and not even miss it.
