Where they actually differ
- They bill on different clocks. Curex charges every 30 days and Willow charges every calendar month. That alone changes what a “month” costs, which is the whole reason this index recomputes every price.
- What they advertise is not what they bill. Curex advertises $199 and bills $405.
How we know

The full working for each — the charge, the period, the arithmetic and the date it was read — is on its own page: Curex and Willow. The method is set out in how we verify.
