💰 Online Shopping Assistant – Auto Coupons & Save Money

A Tampermonkey userscript that helps you automatically save money while shopping online by finding and applying the best available coupons. Supports Amazon, eBay, AliExpress, and Lazada product pages.


✨ Features

  • 🔍 Automatically detects product price on supported platforms
  • 🧠 Finds best available coupon based on product price
  • 💸 Calculates final price after applying coupon
  • 🧾 Supports flat and percentage-based discounts
  • 🧩 Works across multiple stores:
    • www.amazon.*
    • www.ebay.*
    • *.aliexpress.*
    • www.lazada.*
  • 🎯 Injects a “Find Best Coupon” button directly onto product pages

🧪 How It Works

  1. Detects the website you're on (Amazon, eBay, etc.)
  2. Parses the product price from the DOM
  3. Injects a button below the price
  4. When clicked:
    • Matches available coupons
    • Applies the one with the biggest savings
    • Shows final price and coupon code via alert()

🧾 Example Coupon Structure

{
  code: "SAVE10",       // coupon code
  discount: 0.10,       // 10% off (or flat value like 5)
  minSpend: 50          // minimum price required to apply coupon
}
