But when they talk about lack of same-day delivery and make it sound like the lack of Amazon means we're missing out on a superior selection of wares, then I'm not following.
I mean, I wouldn't mind same-day delivery (is this, or next-day, available for every single product, or just a selection of products?), but having to wait a day or two on average is nothing I've personally felt any existential dread about.
Also, it's been years since I noticed that there were products available via Amazon which I couldn't get at a reasonable price from a local online retailer. This used to be the case, but it definitely seems things have improved.
