Gotta admit that mailing a letter is a darn good deal: from your front door to anywhere in the country in 1-3 days for less than two quarters.
That said, thanks to increases I only use about 5 stamps a year. Rates went up one year and I switched almost exclusively to electronic communications.
I hand-deliver as often as possible.
Did you ever allocate the costs for using your computer and internet connection to pay your bills?
Really? Why does it take 5 to 7 days for my expense reports to arrive in San Diego from Pocatello? Most items are 5 days. If it has to be there in a timely fashion, I pay FedEx.
