The price of a D.C. holiday tradition is apparently up to the highest bidder, according to NBC Washington.

NBC Washington found dozens of ads in the last several days alone that listed tree lighting tickets for up to $100 each.

The National Christmas Tree Lighting Ceremony has been held near the White House for nearly 90 years.  It has always been free.

Thursday’s lighting is set to begin at 5 p.m.
