Found a price here that does not match what the gym charges? Tell us and we will re-read the source. Because every figure is re-checked against the operator's own page each night, a correction sticks rather than drifting back.
That is the whole standard: every figure here has to appear on the gym's own website. If it does not, it is a bug and we want to know.
The all-in price exists precisely because the advertised monthly rate leaves fees out. Operators ask. The answer is no.
Intro offers are displayed and labelled, but never used in the comparison — they expire, and building the ranking on them would make it dishonest.
