I think I might cancel. I'm not watching ads and I'm not going to pay the extra $3/mo to opt out. I don't know if I'd end up paying more than the subscription cost in shipping though....
The real trick is you cancel AND shop elsewhere. We get most of our necessities locally now at normal retail and I'll occasionally put an Amazon order together when I need something specific and I'll spend enough for free shipping.
I missed shopping there at first, but so much of their inventory is junk now; I feel like I actually get better quality from traditional retail. The $140/yr for Prime feels like free shipping but it obviously isn't.
Between living in a smaller town and never ending supply chain/distribution issues: If I need something I can't get at the local store, it is a bare minimum two hour ordeal. I can usually justify that on a weekend but if my mouse dies and I need one now? Suddenly I need to figure out what else I can grab to get free shipping or if I need to just eat the costs and overnight it.
I have been doing the math and will likely stick with amazon prime. Admittedly, I increasingly don't bother to even watch the amazon shows I like (the boys and reacher) because I have increasingly become spoiled by a proper blu ray or UHD (... ripped to my plex).
Oh, your computer mouse. Anyway, I just paused my membership in the hopes that my spending habits improve. We'll see how "emergencies" get handled without the shipping benefits.
140$? Why is this so expensive in the us? We pay 90€ (~100$) in Germany. So brake even is with like 20x 5€ shipping orders per year. Which I sadly do pretty easily. Getting the stuff I need locally is sadly not that easy.
