Decoy Pricing.
When presented with two products with equally similar attributes, people often find it difficult to make a decision. It’s often complex to compare and hard work. People tend not to be stupid,
but
they are lazy!
Decoy pricing understands this. Decoy pricinginvolves influencing purchasing decision between two products by presenting a third option — a decoy ‘similar’ to one product but noticeably ‘worse’.

The less attractive decoy isn’t chosen in considered evaluation, but it makes the similar version look more attractive. So if there’s a choice between A and B and I introduce a C (which looks like A, but worse) more people choose A.
