To me as an affiliate this is seen as a slap in the face. if you want someone to become an affiliate advertising on the affiliate network or asking them to sign up as an affiliate after they buy it is the way to do it.
this is most prevalent in Internet marketing products. Mainly because Internet marketers know about how to become an affiliate and what affiliate marketing is. So from here on out, I will never promote a product that has an affiliate link on the sales page because I feel like I'm losing sales almost every single time.
well that's the end of this rant. hope everyone has a wonderful weekend.
