Back in 2010 I bought a book of 20 stamps. Most all my bills get paid thru the internet so I rarely send a letter of sorts. Finally after 10 yrs, I used up the last of the 20 stamps which back then cost me $.42 each. Now I've been buying rolls of 100 stamps at $.55 each. I don't mind the raise in prices, just wish they did a better job in shipping and delivering the mail and packages. But at least my mail persons will ring the doorbell when they leave a package as UPS and FedEx will not and I leave my front inner door open so they know someone is home too.
