## Improvement

1. Only key logics are tested. Not write unit testing for models and helpers.

2. Didn't use any framework, so the service injection is manually done in constructor.

3. Only had a design for database layer, no actual implementation.

4. Promotions are manually loaded in `StrategyService`, not configurable so far.
