Oh looks like the trick is for the # of sales generated on October 31st ONLY
Still not a bad giveaway those with heavy signup traffic can benefit quite nicely
Lets see here
30 days in a month * 10 signups = 300 signups billed 30$ = 9000$
Div by 50% for affils they're making $4500 which I guess is enough for an IPOD + laptop
So I'd definitely promote these guys on October 31st and beyond depending on their conversions.
I think they're also hoping that most people dont buy porn on Halloween
