How do I calculate my total savings for multiple items?

You can use the `get_unit_cost_comparison` tool, which calculates the total savings across all units based on the original price, discount percentage, and quantity.

Can I check if a discount is within my business limits?

Yes, the `validate_promo_viability` tool allows you to check if a discount percentage falls within a specific minimum and maximum range.

How much should an item cost to save a specific amount?

Use the `calculate_threshold_price` tool to find the required original price needed to reach your target savings amount given a specific discount percentage.
