The WRU is coming in for heavy criticism over its ticket pricing policy and playing on a Friday night amid some 10,000 unsold seats for the Wales-France game.
A look at the Principality Stadium map graphic on the Union website shows tickets available across large swathes of the top tier, noticeably so at either end of the ground.
Those left on sale cost £100 and £105 and include a number in the alcohol free zone in the north stand.
