(CNN) -- The U.S. Postal Service raised the price of mailing a first-class letter effective Sunday.
A forever stamp will cost 60 cents when the post office opens Monday.
In addition to the two-cent price increase on first-class stamps, other postal services will also cost more
Everything from postcards to certified mail to money order fees will also be subjected to rate hikes.
The postal service says the rate hike amounts to about a 6.5 percent increase across the board.
They point out the added expense is still less than the rate of inflation, which is nearly eight percent.
