Great. Page after page of detailed information, a request that you sign in for more info, specific info about the delivery day for people in your zip code is provided, and near the bottom of one of the linked-to pages it finally mentions offhand, as if it were just one more great feature, that there is actually a zip code--one zip code--in which the service they've been gushing about is available! For almost everyone, it's a big fat "never mind, we were just kidding!" Wouldn't that be better stated near the top of page one?
A subset of Amazon-fulfilled items hand delivered to my doorstep? I already get that directly from AmazonFresh, where I use such purchases to boost my order size to get free grocery delivery.
It's especially useful when buying booze from them, where the order size minimums are much higher because the delivery must be attended — instead just leaving it in a plastic crate at my doorstep, the driver puts it in my fridge for me.
I probably won't ever use this unless it covers close to the full set of Prime-eligble items, which would involve them keeping no local inventory unlike what they're doing with Fresh already.
Note: this is not a subset of Amazon-fulfilled items as with AmazonFresh, this is pretty close to everything that Amazon ships. (It's basically just Amazon delivering otherwise super-saver shipments the last mile to your door using their own trucks, where available).
To which I say "hooray!" Amazon seems to LOVE my zip code. It's a cozy part of Seattle's Capitol Hill neighborhood centered around a more residential experience than what the Hill is usually known for. I'll be using this. Especially as a Prime member.
EDIT: Oh! It's only available there. That's odd. I signed in and they told me my day was Wednesday, even though all me addresses are in Oregon. Oh well.
