When quizzed about postal stamp rates, new Postmaster General Louis DeJoy said he didn’t know the cost for a postcard or a square greeting card, though he did know the rate for a first-class mail stamp.

But it is important to you – and to me – to understand the costs and “ins and outs” so that we can keep track of our expenses. I’ve included in my price charts below the number of sheets of plain paper that will fit in an envelope at each weight/price level.

Postage will be going up as of August 29, 2021. Here is a chart showing the increases:
