How Browser Extensions Find Coupon Codes Automatically
The Magic Behind Auto-Apply Coupons
Browser extensions like Honey, Capital One Shopping, and our own tool scan thousands of coupon databases when you reach a checkout page.
How It Works
Extension detects you're on a checkout page
It queries a database of known promo codes for that store
Codes are tested one by one in the promo field
The best working code is applied automatically
The entire process takes 10-30 seconds and can save you an average of $12 per order.
