The main part is article 7.4 "When assessing whether consent is freely given, utmost account shall be taken of whether, inter alia, the performance of a contract, including the provision of a service, is conditional on consent to the processing of personal data that is not necessary for the performance of that contract." which is a bit tricky legal language to make the distinction between PII use that's actually needed to perform the contract (which doesn't need consent, e.g. address to deliver goods) and uses beyond that (e.g. using the same address afterwards for ad targeting). The final part of recital 42 "Consent should not be regarded as freely given if the data subject has no genuine or free choice or is unable to refuse or withdraw consent without detriment." is probably even more clarifying than recital 43.
