Would it be feasible to use a combination padlock and send the number as a part of the address/shipping note?

I'd doubt delivery drivers would have the time. They already sprint to the door with the package or drive right up.

Maybe? Kind of doubt it, though. Plenty of places don't have a delivery-instruction field and a lot of deliveries (again lookin' at you, Amazon) are barely delivered at all. "Chuck it on the front step and go."

Well, there's always Amazon Locker for those cases. A little less convenience for a little more assurance.

And that's annoying, for sure, but most of the time the box would still work though, right?

Well, this happened both today and yesterday, 'cause my roommates and I don't really sync up our online purchases...;)

I'm pretty sure Amazon explicitly offers the option to "group my items into as few shipments as possible, even if it takes longer".

As few as possible is sometimes still more than one, though.

Why does this happen? Are the items coming from multiple Amazon locations?

> Are the items coming from multiple Amazon locations?

Yep! Especially if you live in NYC (or anywhere in the North East really). Amazon has something like 50+ different warehouses in NJ and Pennsylvania alone.

I searched for that option recently and couldn't find it. Could you give the exact path through the menus?

As far as I remember, the option appears when you're checking out and choosing your shipping. It's per-order, not per-account.

Thanks. Hmm. It wasn't very obvious then.

Doesnt work if they are coming from different warehouses or are too big for one box.
