Reviewers see Couponly as a practical, low-friction coupon extension that does the basic job well: it finds codes, tests them, and applies what works at checkout without sending users through messy coupon pages or long code lists. Several say the appeal is its simplicity and background automation, especially for people who usually forget to check for discounts. The main criticisms are narrow but repeated: support needs improvement, and one reviewer wants a better interface. Overall, feedback is positive but still early and focused on core usefulness.
Love how the browser extension actually tests codes before applying them, that small detail saves a lot of frustration compared to the usual coupon tools that just throw expired garbage at checkout.
