A referral is a way to find customers
Instead of paying only for conventional advertising, a company can reward an existing customer who introduces someone new. The company expects the new customer to stay and buy enough over time to justify the incentive. That explains why rewards often arrive after a switch, a first delivery or a paid subscription.
Why the reward can be uneven
Some providers reward both people; some reward only the inviter. The customer-facing benefit may be a free trial while the referrer receives a later plan discount. Look at our ClassPass listing for an example where the referrer’s benefit depends on the new member paying after the trial.
Ask whether the offer is saving you money you would otherwise spend. An incentive is not proof that the product is the best fit.
The conditions reveal the business goal
An energy supplier wants the switch to complete; a meal subscription wants a first paid box; a financial app may ask for several genuine purchases. These steps are not interchangeable. If you would have to make purchases you do not want just to qualify, subtract that cost from the reward.
Be clear about the commercial interest
When a personal link appears on this site, the card discloses what the owner may receive. That disclosure lets you compare a referral with a public offer. Use the provider’s terms and the actual checkout for the final decision, especially when the offer has changed since the page was reviewed.
