Questions

ReferBonus FAQs

What is a referral code?: A referral code (or referral link) is a unique identifier existing customers share so a brand can reward both sides when a new customer signs up. You typically get free cash, credit or a discount, and the referrer gets a similar reward — the brand pays for both as a cheaper alternative to advertising.
Are the referral offers on this site free to use?: Yes. Using a referral code or link never costs you anything — the rewards are funded by the brands' marketing budgets. Some offers have qualifying conditions, like a minimum deposit or a first purchase, which we spell out on every offer page.
How do you make money?: When you sign up through some links on this site we may receive a referral reward ourselves. That's our whole business model — it never affects the price you pay, and we show the same qualifying conditions the brand publishes.
How often are offers updated?: We review offers regularly and show a 'last updated' date on every page. Brands do change or pause schemes at short notice, so always double-check the terms on the brand's own site before signing up.
Can I share my own referral codes here?: Not yet — right now we curate offers ourselves so we can check terms and keep quality high. A community submission feature is on our roadmap.
