Terms & Conditions

Items authenticated through D-backs Authentics will be made available for purchase at the sole discretion of the Arizona Diamondbacks. Availability changes quickly and items are never guaranteed.

In addition, any information published or made publicly available by the MLB Authentication Program or its MLB.com Referencing System is not an offer for sale. Items listed in the MLB.com Referencing System may include items previously sold or items withheld by one or more MLB Clubs for internal use or for any other purpose in the discretion of the withholding Club. This information is for informational purposes only and designed to distinguish officially authenticated MLB memorabilia from other items on the market but is not a representation that any item is available for sale.

Without limiting the foregoing, any items offered by D-backs Authentics are a contingent offer. For example, items offered for sale prior to a game may, during the game, achieve historical significance to Major League Baseball, the Arizona Diamondbacks, its individual players, and/or the National Baseball Hall of Fame. Accordingly, D-backs Authentics reserves the right, in its sole discretion, to cancel any pre-order based on the request of the Arizona Diamondbacks, its players/coaches/managers, Major League Baseball, or the National Baseball Hall of Fame. In such event, the applicable order will not be fulfilled and the full amount of any purchase will be refunded at the end of the game.
