You can still buy from Amazon as needed without Prime. The free shipping is still usually relatively fast, and they'll give you a free or heavily discounted Prime trial fairly often. I try to avoid buying stuff on Amazon these days, but a lot of things simply aren't available elsewhere or would be significantly more difficult to acquire. I haven't had a steady Prime sub in at least a couple years, but they end up offering me a trial probably every few months. Hell, they gave me a full month for free a week ago (probably to try to drive up Prime Day sales).

This. Trying to find anything in a brick and mortar store in the last decade has been such a godawful experience that I don't feel the least bit sorry for them. Groceries are largely delivered (not using Instacart, but the store's own delivery or pickup service), tech stuff is all aliexpress or amazon, clothing I still largely go in to buy, but don't buy very often. Appliances? Research the shit out of it online and usually order online from a local retailer with a decent website. Heck, even hardware is online through Home Depot and auto stuff is either rockauto or similar.
