Not too long ago, my daughter at college lost her favorite headphones. For reasons not worth going into, we needed a replacement fast so I went to Amazon. I figured that Prime shipping would be able to get the kind she likes to her before I could get there myself (I was some hundreds of miles away but planning to swing by on my way home). Isn't that what I paid the subscription fee for? Well ... no go. IIRC the best they could do was four, maybe five, days. And not because they were out of stock. Then I went to B&H, who could get them there next day for a better price. No prizes for guessing who got my business that day.
Amazon was a pretty decent bookstore once, then a pretty decent "everything" store, then they just enshittified the hell out of everything. While it's good that anti-trust actions are finally being taken, it would have been even better if the practice of predatory pricing sustained by VC money (not just at Amazon) had been nipped in the bud long ago.
