Listings are limited while founding businesses come on board. You can filter what is live by category, by country and region across the United States, Canada and the UAE, by payout, and by distance from where you are. If nothing matches yet you can leave your email and hear when offers go live in your area.
Open an offer, read the reward and the qualification criteria the business set, then submit the customer's details on that business's referral page. The business qualifies and works the deal and pays you the full advertised amount directly when it closes.
Publishing your referral page and appearing in the marketplace is free. Set your offer and your reward, publish, and referrers can find you. Revvin Pro is available at $49/month USD for the tools that ask your whole customer list for you.
