Some links on this site earn a commission when someone subscribes through them. It costs the reader nothing and it does not affect the rankings.
Rankings come from the engine that reads the stored ladders. There is no field in the data for what a platform pays, so there is nothing a commission could move. Platforms with no affiliate programme at all are included on the same terms as the rest, because a comparison missing the obvious options is not a comparison.
Where a platform publishes no price — a plan sold by quote, or a size above its published ladder — this site says so rather than estimating.
The code that collects the prices and the data it produces are both kept under version control, so every figure can be traced to the day it was read.
