We just hassled them about charging for PCI compliance and this is the response we got:
This is to informed you that PCI Compliance is not required by Intuit. We just strongly advises that our account holders/merchants to be PCI Compliant. Intuit is compelled to send out notifications to the merchants about it.
Intuit does not charge for PCI Compliance thus, we will not invoke penalties if you are not a PCI Compliant.
