What this video covers

The decoy effect occurs when adding an asymmetrically dominated option - clearly worse than one choice but not worse than every alternative - makes the option that dominates it more attractive.

With two plans, the bundle looked dear and you leaned towards digital. Add a print-only plan at the same price as the bundle - plainly worse - and the bundle suddenly reads as a steal. Nothing about it changed. The decoy just handed you an easy comparison to win, and your eye took it.
