Selecting a non-discounted meal bundle increased purchases of products outside the bundle by causing shoppers to underestimate total basket size.
What this does not establish
Food and meal bundles, experimental baskets and item counts do not establish revenue, contribution margin, repeat purchase or waste outcomes.
Counterevidence & uncertainty
The basket lift occurred without a price discount, but only when shoppers selected a bundle; merely displaying bundles is not equivalent to universal incremental sales.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
