Assumptions & Methodologies
We analyzed our U.S. e-receipt panel on July 20, 2026, covering July 2025 through July 20, 2026. The cohort comprised 2,540 panelists with America’s Test Kitchen, Cook’s Illustrated, or Cook’s Country membership or subscription signals who were observed before July 2025 and had receipt activity from June 20 through July 20, 2026. The benchmark was 646,206 other active digital subscribers. We converted each original index into a multiple by dividing it by 100. Platform receipts identify the service, but not the underlying restaurant or grocer.
