As of 2014, the U.S. Postal Service offers postage stamps in rolls of 100, 3,000 and 10,000 stamps. Most stamp rolls contain self-adhesive stamps and can be purchased in many denominations.
USPS issues many first class stamps as Forever Stamps. Forever Stamps retain their value even if postal rates rise. Most rolls of first class stamps, including the rolls of 10,000 stamps aimed at businesses, are now issued as Forever Stamps. This makes purchasing stamp rolls an economical choice since they stay valid until the roll is finished, even if postal rates change. USPS issues rolls in other stamp denominations as definitive stamps, meaning in actual amounts, rather than as Forever Stamps.
