Is that really so hard? I cancelled my Prime subscription years ago and haven't missed it. Walmart, Target, Costco, BestBuy, HomeDepot, etc haven't gone anywhere. Smaller specialty retailers usually sell on their own website with shipping too. Plus, one genuine advantage the other retailers have over Amazon is that you can (usually) trust you're getting something of reasonable quality, whereas Amazon feels like an AI generated flea market filled with garbage quality Aliexpress drop shipping schemes.
I thought losing two day shipping would suck, but it really hasn't. Most of the big retailers (in my area anyways) end up delivering online orders in two days or less anyways, and the delivery fee is free if your order is over a certain size (usually around $35)
De-googling or De-appleing is hard, but De-amazoning (at least for me) was trivial and anticlimactic.
