There are several reasons why someone might consider getting involved in affiliate marketing:

1. Low startup costs: Affiliate marketing typically requires minimal upfront investment. You don't need to create your own product or service, handle inventory, or manage customer service.

2. Passive income potential: Once you've set up your affiliate links and promotional channels, you can potentially earn passive income as long as people continue to click on your links and make purchases.

3. Flexible work schedule: Affiliate marketing allows you to work on your own schedule from anywhere with an internet connection. 

4. No customer support: As an affiliate marketer, you're not responsible for handling customer inquiries, complaints, or returns.

5. Unlimited earning potential: There's no cap on how much you can earn with affiliate marketing. Your income is directly proportional to the effort you put into promoting products.
