Always worth the going rate.
The PERMANENT™ stamp, identified with the letter P in place of a value, is always accepted at the current domestic postage price. So if you buy a PERMANENT stamp today, you can still use it in at any time in the future—no more 1 cent stamps when the postal rates increase.
Self-adhesive PERMANENT stamps are available in booklets as well as in coils of 100 stamps. One stamp can be used to mail a letter anywhere in Canada that weighs up to 30 grams or more postage can be added to mail larger letters, parcels or to send mail internationally.
