Amazon delivery times

I have the least problems with the USPS, except when it's a Sunday delivery because the carrier that day is trying to get off as soon as they come on. They will put the package in the parcel locker (I love in an apartment complex), but instead of putting the locker key in my mailbox to retrieve, they just stick the key in my box lock so anyone could take it. It's at the point that if I see something is set for a Sunday delivery, I'd just wait until time elapse and it becomes a Monday delivery.
