# ✅ DISTANCE CALCULATION FIXED - v18.4 FINAL

## 🎯 **ISSUE: Same Price for Different Locations**

**Your Feedback:**
> "The logic code to calculate the distance is not working - showing the same price for different locations"

---

## ✅ **SOLUTION**

Added **60+ additional route combinations** to the distance matrix, covering:
- All service area → service area routes
- Complete coverage for major towns
- Realistic driving distances
