Hey, I am new to CPA, so I have a noobish question, what is the difference between these two offers? First one: http://postimg.org/image/9rfy7m2yv/Second one: http://postimg.org/image/lhtvozvrb/ When EPC is $0 and CR is at 0%, the offer is worthless? Can't money be made from that offer? What exactly is EPC and CR? Thanks in advance.
