Reply #41: here is how it breaks down for us

[Tailormyst]

.357 cents per regular letter with return envelope included. Then for each one returned there is a cost of .74 cents.

First class rates are .42. The bulk rate also allows that we only pay return rates on those returned instead of a prepaid envelope of .42 cents each.

It might not seem like much of a difference but there is, especially for a small business. And frankly, these mailings are what keeps the Post office going and what lets you send a Christmas card for .42.

I would rather see them not deliver on Saturday, it makes more sense.
