A practical workflow

If you want the best buying decision, use:

1. Google Shopping to scan prices/options
2. Wirecutter / Consumer Reports / RTINGS for quality testing
3. Amazon reviews or retailer reviews for real-world feedback
4. Keepa/CamelCamelCamel to check whether the price is actually good

If you want, I can also give you:

• the best sites by category (electronics, clothing, home, etc.), or
• a top 5 list focused only on unbiased product discovery.
