Partners
Affiliate program
Duple is free to use. The platform is funded by referral commissions from purchasing agents and affiliate partners.
How we earn
When you add an item to cart through an agent using a Duple referral link, the agent may pay us a commission on qualifying purchases. This is our primary revenue source.
Commissions never change the price you pay — they are paid by the agent or marketplace out of their own margin.
Our editorial independence
Search results are ranked by relevance, price, and community signal — never by commission rate. Sponsored placements, if introduced, will always be clearly labeled.
