Their pricing can differ by region. Not every region got the data caps back when they rolled them out.
It also depends on competition - if there’s a lot of competition in your area, Comcast will have better deals compared to if you live somewhere where Comcast is the only option.
I used to live in an apartment that had an exclusivity deal with Comcast (residents were only allowed to use Comcast for internet service). Now I live somewhere in the same county where there’s three different fiber providers in addition to Comcast, and their prices here are noticeably cheaper vs the old apartment.
