1. **Compare prices:** Use `--json` output to programmatically compare across retailers
2. **Find best deals:** Look for high `discountPercent` values
3. **Check availability:** Use `--zip` with local ZIP code for accurate results
4. **Wildcards for variants:** Use `Jogh*` to catch Joghurt, Joghurtdrink, etc.
5. **OR for alternatives:** `Butter OR Margarine` to compare substitutes
