Thanks dear. These ones run for 21 cents a piece. At one time they were 22 cents but they went down in price a little bit. I wish that was the case with regular forever stamps.
You could also add these ones as bonuses but with these ones you have to go to the post office or order them online. I just been getting these when I do my packages. I use some and sell some and these ones are fairly cheap to buy. Only a little over $4 for a sheet of them if you get them at the post office. If you get them online then they are more expensive unless of course you buy them from me on here. I think I'm the only one selling ounce stamps but these would cover extra if something needs a little extra ounce.
I know! I wish others would list them so people don't have to use 2 regular stamps to cover the cost of a letter whether it's machinable or non machinable. I use these for my non machinable letter items.
