Product Shield: Brand Tax Detector

Automatically detects overpriced brand-name items on Amazon and finds the generic equivalent to save you 50% or more.

Product Shield: Stop Paying the "Brand Tax" Save 50% or more on Amazon by finding high-quality generic equivalents in real-time. Product Shield is a smart shopping assistant that lives on Amazon. It automatically detects when you’re looking at a brand-name product—like a $150 hair dryer or a $200 rug—and finds the identical "generic" or "brand-equivalent" version available at retailers like Walmart for a fraction of the price. Why use Product Shield? Automatic Detection: No searching required. If a better deal exists for a generic equivalent, a small, non-intrusive "Shield" appears on your screen. Real-Time Math: Our algorithm factors in shipping costs and price gaps to ensure the savings are actually worth the switch. Privacy First: We don’t track your personal data. We only look at the product you're viewing to find you a better price. Clean & Lightweight: No bloat, no ads, and no slowing down your browser. How it works: Install Product Shield. Shop on Amazon as you normally would. When Product Shield finds a generic equivalent that meets our "High Savings" criteria, you'll see a notification with the potential savings. Click "View Deal" to see the equivalent item and keep your hard-earned money. Transparency & Disclosures Product Shield is a community-supported tool.
