Instacart has faced various legal challenges and consumer class-action lawsuits regarding its fee transparency, particularly concerning how "service fees," "delivery fees," and product markups are communicated to consumers. Plaintiffs in these cases have argued that the company historically lacked transparency in how these costs were described, alleging that they were not clearly distinguished from original grocery store prices or were structured to mislead customers regarding total final costs. Instacart has consistently defended its pricing models, asserting that its terms and conditions clearly disclose fee structures, but such legal disputes remain a recurring feature of the gig-economy e-commerce space as regulators increasingly demand stricter disclosure standards.
