Different plan prices on Apple website vs Verizon when changing to Unlimited Plus

When I look at verizon's website to update to Unlimited Plus, it shows that my new monthly will be $42/mo. Currently on 5G Do More ($44/mo). When I'm ordering iPhone 16 pro on apple page it shows $80/mo, whats going on?

It shows the message below, which should mean that its $55.02/mo, but its saying $80/mo.

Verizon device payments will be $13.02/mo.per month over 36 months at 0% APR within two monthly payments of $34.69

I have 6 lines on the account, is it because of family discount or something?
