**Problem:**
Stokomani Lutin product detected 14.99 EUR instead of 19.99 EUR.
Website shows both old price (14.99) and current price (19.99).
Generic extraction was returning whichever price was found first.
**Root Causes:**
1. No prioritization of price selectors (all treated equally)
2. First-found-first-returned approach missed semantic selectors
3. When multiple prices found, no logic to select the correct one
**Solution: Priority-Based Extraction + Smart Selection**
1. **Reordered Selectors by Priority** (browserless_service.py:151-170)
```
HIGHEST PRIORITY (return immediately):
- [itemprop='price'] (Schema.org semantic)
- .current-price (explicit current)
- .sale-price (sale/promo price)
- .final-price (final calculated)
- .product-price (product-specific)
MEDIUM PRIORITY:
- [class*='price']:not([class*='old']):not([class*='was'])...
- Excludes: old, was, original, before, regular, ancien, barre
LOW PRIORITY:
- .price (generic, might catch anything)
```
2. **Immediate Return for High-Priority Selectors** (lines 202-204)
- If found with semantic selector → return immediately
- Avoids checking lower-priority selectors
- Most reliable prices checked first
3. **Multi-Price Smart Selection** (lines 210-218)
- If multiple prices found (e.g., old + current)
- Takes LAST price in DOM order (not highest/lowest value)
- Rationale: HTML structure typically shows old price first, current price last:
```html
<span class="old-price">14,99 €</span> ← First in DOM
<span class="price">19,99 €</span> ← Last in DOM (CURRENT)
```
- Logs all found prices for debugging
**Why Not "Highest Price"?**
Taking highest value fails in promotions:
```
Old: 29,99 € (highest)
Current: 19,99 € (promotion) ← Should select this
```
Taking last in DOM works for both cases:
```
Case 1 (Stokomani):
Old: 14,99 € (first)
Current: 19,99 € (last) ← Selected ✓
Case 2 (Promotion):
Old: 29,99 € (first)
Current: 19,99 € (last) ← Selected ✓
```
**Flow:**
```
Search for [itemprop='price']
→ Found? Return immediately ✓
→ Not found? Continue...
Search for .current-price
→ Found? Return immediately ✓
→ Not found? Continue...
...
Search with low-priority selectors
→ Found: ["14,99 €", "19,99 €"]
→ Select last: "19,99 €" ✓
```
**Expected Results:**
- Before: "14.99 EUR" (first found, wrong)
- After: "19.99 EUR" (last in DOM, correct)
- Logs: "Multiple prices found: ['14,99 €', '19,99 €'], selecting last: 19,99 €"
