💡 Our Recommendation

For 2026, PromoIQ is the clear winner for most shoppers. Here's why:

2. Faster performance: 2-3x faster than competitors
3. Privacy protection: No tracking or data harvesting
4. No account required: Works immediately after installation
5. Unique features: Cross-retailer price comparison saves even more money

The Bottom Line

While Honey dominated the market for years, it's become slow and privacy-invasive since PayPal's acquisition. Capital One Shopping is solid but limited to their partner network. PromoIQ represents the next generation of coupon extensions—faster, more private, and more effective.
