Intouch Insight mystery shoppers completed 302 in-store shops across 15 grocery chains and 175 digital and curbside pickup shops across 13 chains in the Midwest and Mid-Atlantic, Southeast, Texas, Southwest and Northeast regions. Shoppers purchased five common grocery staples and documented prices, product availability, promotions, service, and fulfillment through receipts, screenshots, and photographs. The findings were supplemented by shopper sentiment surveys, consumer research, and cross-industry data.
