What is the best way to get more rewards from the distinction and commendation certificates in Arknights?

### Certificate Strategy: 1. **Distinction Certs**: Save for high-value items. 2. **Commendation Certs**: Use for daily necessities and permits. 3. **Balance**: Don't spend everything at once, plan your purchases.

Always keep an eye on the shop refresh. Sometimes, limited operators become available, and you'll want to have enough certificates to snag them.
