Add TSA PreCheck to your office-supply list. Retail giant Staples recently announced the opening of IdentoGO centers in 50 stores across the U.S., allowing travelers to enroll in the program without a reservation or an additional trip to the airport. Added bonus: The in-store centers also offer passport photos and certified birth certificates. Look for them in major metro areas such as New York, Boston, Chicago, Dallas, Los Angeles, and Seattle, with more to roll out in the near future. TSA enrollment fee (valid for five years), $85.
