Between just those 2 sites that gives you 11237 unique visitors a day..if 25% spend 30.00 that's over 30 million a year..most of the packages on there are more than that or around that price..so that's a pretty conservative estimate imo.
That doesn't take anything into consideration as far as wholesale goes..and from what I've seen, that seems to be a large part of the business...holy moly batman!
