 Ideal for retail environments running promotions such as 'Redeem X points for 1 Free Item'. By default, if a user has 3x points, Odoo allows them to claim 3 free items at once. This module strictly restricts the reward so only 1 free item can be claimed per transaction, exactly matching the configuration in the backend.
