Refersion Affiliate Marketing

My company sells handmade custom skin care products like facial serums for a wide variety of skin types. In order to reach a wide market we are using affiliate marketing. I was searching for an alternative to Share-A-Sale which has a steep startup cost ($600). This one lets you start off as low as $19/month. I don't like that an affiliate cannot combine an affiliate link with a personalized discount code, but otherwise I am finding it a great solution. Also, the customer service is responsive.
