How many pages can you ship with a 42 cents stamp?

The limit is based on weight -- one ounce maximum. Two standard sheets will almost

certainly weigh less than one ounce, but I found that my Christmas cards plus a

2-page letter was too heavy. Three thin sheets might be under an ounce- you would

have to weigh it for sure.

Postage scales are not very expensive, and they have a free one at the PO.--I think that mine has probably paid for itself more than once is saving on postage.

By the way , the second ounce only costs 17 cents extra- I know people who put

a second 42-cent stamps just to make sure.
