Can I return an opened access card or shrink-wrapped item? 

  • Some shrink-wrapped items may still be returned. These must be in original condition with all items present and may be subject to a shrink-wrapping fee. 
  • We recommend using the trial for any online access before using an access code in case you need to return it. 
  • Access cards are not returnable once scratched or opened.
