USPS To Start Delivering Packages On Sundays!

So we've all heard that the USPS is going to scale back mail delivery to 5 days a week, but will continue to deliver packages on Saturday.

Now, we're being told by the PMG that there is a new development in that packages will soon be delivered on both Saturdays and SUNDAYS, too (in some areas)!

If the USPS can afford to deliver packages 7 days a week, even if its only limited to certain areas, but has to scale back mail delivery to 5 days a week, I just wonder what kind of net savings they are realizing in doing so. They're expanding package delivery and reducing regular mail delivery. So where's the savings?

Seems counterproductive to me.

There is a vast difference in quantity between packages and sorting and delivering the rest of the mail. Does UPS or Fed-X stop at every house, every day? And it will lighten the load for Monday when three days worth of regular mail need sorting and delivering.

Somewhere in all the articles I have read, the statement was made that the package delivery was profitable for the USPS, hence continuing to deliver on Saturday and now apparently on Sunday.

I've seen the big UPS trucks leaving my local post office a few times.

I still find it odd. My regular carrier drops off packages during his mail run, in my case leaving a note on my mailbox since I live in an apartment complex. I think the regular carrier does express mail too, at least on weekdays. So now we'll have mailmen on the weekend who just stops around the area like what UPS trucks do, with packages only? If it's Sunday I hope they go to my door instead of leaving me a note.

What is a package, a small first class box, or does it start right at parcels?
