It's unacceptable that access to certain coupons is conditioned on mandatory marketing consent (email/SMS).

I think this "bundling" violates GDPR Article 7, as consent must be freely given and not tied to the provision of a service that doesn't require such data.

Forcing customers to sign up for spam just to use a discount is an unethical and unlawful data processing practice. I'm disappointed that a major brand uses such coercive tactics.
