Amazon offers downloads of Fallout: New Vegas for Xbox One and Xbox 360 for $3.74. That's $8 under the lowest price we could find for a physical copy of this game.

Also available are downloads of Fallout 3 for Xbox One and Xbox 360 for $3.74. That's a buck under our June mention and the lowest price we could now, also by $1. Both games are part of Xbox One's backwards compatibility program.
