How exactly do CPA offers work in the US? And I'm asking about E-mail / ZIP submits because I only see those kind of offers for the States, most of EU has no ZIP/E-mail. For example, the typical mobile offer (which we have in EU) takes money from the visitor, by overcharging SMSs, crediting the advertiser, the publisher and the network with money from the visitor. But on ZIP / E-mail offers, who pays those $1,xx? And where does it take those money from? I also saw some campaigns (from Customer Incentive Rewards if I remember well) which after the ZIP was entered, they were bringing up additional affiliate offers which basically required the visitor to buy something in order to get that prize for free. But since the visitor wasn't really interested in buying (rather than getting a free XBox for example), those $1.xx seem to be considered loss. I'm asking because I'm thinking of implementing something similar in my country. Maybe I would pay less for my leads but traffic is definitely comprised of stupid people and since this form of scamming is very legal, I'm thinking it can become rather profitable.
