Comment Comment by yencabulator The word "stamp" is confusing here.You put postage on the letter, and the post office stamps the postage (to invalidate the postage). The stamp contains a date. You can't stamp something after having mailed it, that happens as part of the mail submission. parent yencabulator 2 years ago
