MarketWatch reports that “Walmart Inc.'s Sam's Club is now delivering alcohol, including wine, beer and spirits, via Instacart in select markets across states, including Florida, California and Missouri … Consumers can get same-day delivery of alcohol alongside their groceries with plans to expand the service to additional locations in the coming months.”

Offering alcohol delivery? Good idea. Allowing Instacart to make those deliveries and access your sales data and co-opt your customers? Not so good. Even if you are Walmart.
