Why is it free?
There is no paid plan and we do not sell your data. When you buy through a partner pharmacy link, the chain pays a commission — and that never changes the ordering, which always runs cheapest first.
Ordering always runs from lowest monthly cost to highest. Partner pharmacy commission never changes it.
