## Summary

Active users of grocery loyalty apps (Lidl Plus, Rewe, Netto, or Penny) averaged a €27.28 grocery basket in 2026, compared with €31.32 for non-users — 13% smaller by mean and 18% smaller by median (€13.31 vs €16.17). The gap is specific to grocery: the same two groups spent virtually identically across all retail categories combined.

## Why app users buy less per trip, not less overall

Aldi Süd's "Günstig ohne Bonus-App" campaign claimed that loyalty apps lead shoppers to spend up to 30% more — a figure cited in the Aldi press release referencing third-party loyalty research. The basket data here tells a different story: grocery loyalty app users average smaller baskets per transaction, not larger ones. A likely explanation is selection: shoppers who actively open loyalty apps tend to be more price-conscious, making more frequent but smaller shopping trips and splitting purchases across stores to chase coupons. The Verbraucherzentrale Bundesverband has noted that the real monetary savings from grocery apps often fall in the 0.75–2.29% range per shop — modest enough that active users may be optimising trip frequency rather than basket size. The absence of any basket-size gap across all retail categories confirms this is a grocery-specific behaviour pattern, not a general difference in purchasing power between the two groups.

## Chart

Bar chart comparing mean and median grocery basket size (in euros) between active grocery loyalty app users (Lidl Plus, Rewe, Netto, or Penny app openers) and non-users, based on email receipt data from January to August 2026. Active users: mean €27.28, median €13.31. Non-users: mean €31.32, median €16.17. A separate comparison panel shows near-identical basket sizes for the same two groups across all retail categories.

## Methodology

Grocery basket size is measured as the per-order spend in euros derived from email receipt data, covering purchases at the four grocery loyalty app retailers (Lidl, Rewe, Netto, Penny) from January to August 2026. Orders are deduplicated by order number and capped at €2,000 to remove clear outliers. Active loyalty app users are defined as those who opened at least one of the four apps at least once in the observation period. Non-users are drawn from the same population, with no app opens recorded for any of the four apps. Both groups are compared on grocery spend and on total spend across all retail categories.
