What is the difference between CPC & CPA retailers?

For cost-per-click (CPC) retailers, you make money every time someone clicks/swipes on your link. The rate is determined by clicks vs performance. For commission-based (CPA), your earnings are determined by the number of products sold. The CPC rate is listed by the amount you are paid per click (i.e., $.09), whereas CPA retailers will show you the percentage you will get per item. *Note, not all products are commissionable, so please check before posting.
