- **Deduplication**: deals are tracked by game ID + timestamp; duplicates are never reposted
- **Pruning**: deals older than 30 days are pruned from the database so they can be reposted if they return
- **One message per deal**: each deal is posted individually so messages are independently linkable and dismissible
