Primary Outcomes
Primary Outcomes (end points)
- The probability to purchase at the shop.
- The probability to redeem the rebate conditional on purchasing at the shop.
- Whether purchase value is above the minimum order value.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
- Revenue.
- Profit.
- Quantities purchased by each product category.
- Total quantities purchased (all categories pooled together).

Dynamic effects will also be reported. The outcome variables are:
- Probability to buy again at the shop within the experimental period.
- Probability to redeem the rebate on the follow-up purchases.
