Starting today America’s official mail agency is partnering with our former colonial bosses by agreeing to sell official commemorative wedding merchandise produced by the United Kingdom’s Royal Mail.

Postal customers can visit USPS.com/shop to purchase a limited supply of Royal collectibles, including a brochure, sheets of stamps and envelopes with the official wedding postmark and stamps.

A brochure selling for $7.95 features the two official engagement portraits by photographer Mario Testino.

Sheets of the official stamps with Prince William and Katherine Middleton cost $6.95. An envelope with the official wedding postmark, a Wedding Roses Forever Stamp and two Royal Wedding stamps issued by Royal Mail costs $4.95.

Stamp collecting remains a popular global pastime and stamp sales generate between $250 million and $300 million annually for the Postal Service.
