📌 How It Works

1️⃣ Collects product URLs

• AM.py scrapes Amazon product links
• GS.py scrapes GameStop pre-order links

2️⃣ Scrapes product details

• amazon.py extracts title, price, availability, image
• gamestop.py extracts product data using Selenium

3️⃣ Compares with previous data

• If a new product is found or price changes, it's stored in SQLite

4️⃣ Sends a Telegram alert

• 🚀 Users get notified instantly

📊 How Data Is Processed

🛒 Amazon Scraping

• AM.py collects product links & filters relevant products
• amazon.py scrapes title, price, availability, image
• If price changes by more than 5%, an alert is triggered

🎮 GameStop Scraping

• GS.py scrapes pre-order product links
• gamestop.py extracts product data using Selenium
• If the product is no longer available, it’s flagged in the database

🛠️ Configuration

🔹 Modify tracked products

Edit the keywords in utils.py:

KEYWORDS = ["pokemon", "booster", "elite trainer box"]
EXCLUDED_KEYWORDS = ["random", "assortita", "Heartforcards"]

🔹 Change price change threshold

Modify the percentage in processing.py:

PRICE_CHANGE_THRESHOLD = 0.05  # 5% price change required for notification

🔹 Enable/Disable sites

If you want to disable GameStop tracking, remove run_gs() from main.py:

await asyncio.gather(track_products(), run_am())

🚀 Future Improvements
