Automated EAN/ASIN bookmarklet

Ever stare at a "Black Friday deal" wondering if it's actually a good price? Let's be honest - not every "deal" delivers the savings it promises. That's why we've developed a free tool that makes it incredibly easy to find and compare product codes across major retailers.

The Challenge

Many online stores hide their product identification codes (EAN, GTIN, UPC) in their source code, making price comparison tedious and time-consuming. Our solution? A simple yet powerful bookmarklet that automatically uncovers these hidden codes.

Key Features

1. Instant product code detection

• Reveals hidden EAN codes from source code
• Supports Amazon ASIN codes
• Identifies bol.com BPIDs
• Discovers EAN/GTIN/UPC codes

2. Easy price comparison

• One-click deeplinks to Amazon
• Direct bol.com price comparison
• Integrated Google Shopping verification
• Single-click code copying functionality

3. Time and money Savings

• Compare prices across multiple retailers
• Eliminate manual search efforts
