I don't mind that they have to make some dough, BUT...this particular pop up is so annoying I don't see anyone ever buying their product. One or twice a session is enough, then people might pay attention, I've had it show up two-three times while reading a single post (way too much) and at least once every time I switch to a different post. I don't care what it is, any thing that annoying is NOT getting the desired result from most people.
