What's the difference between GBL § 349 and § 350 claims?

GBL § 349 prohibits deceptive acts or practices generally (broad conduct), while § 350 specifically targets false advertising. § 350 requires proof the misrepresentation was in an 'advertisement,' while § 349 covers any deceptive business practice. For false marketing, you can allege both statutes. § 350 is more focused; § 349 casts a wider net.

Do I need to prove I personally relied on the false advertisement?

Courts are split on this. Some require individualized proof of reliance, while others allow a presumption of reliance for material misrepresentations. Generally, if the false claim was material (important to purchasing decisions) and consumer-oriented, reliance may be presumed. However, be prepared to explain how the false ad influenced your purchase decision.

Can I sue for false advertising even if I didn't lose money?

Yes, if you suffered harm. Harm can include paying more than the product was worth (diminished value), receiving a different product than advertised, or incurring costs because the product didn't work as claimed. You need actual damages, but they don't have to equal a total loss. Even a $50 overpayment due to false advertising is recoverable.

What if the business claims their advertising was just 'puffery'?

Puffery—exaggerated claims no reasonable person would take literally (e.g., 'world's best pizza')—is not actionable. But specific, measurable claims (e.g., '50% off,' 'made in USA,' 'FDA approved') are not puffery. Courts look at whether a reasonable consumer would rely on the claim. If it's a concrete factual statement, it's likely actionable if false.
