I've been monitoring the WaFo scene for a few months now while pushing the big ticket ($2k+) launches via SEO/PPC, it's really quite fascinating in it's scope and scale.
Every single day of the week (minus Sunday, they rarely push hard on Sunday's for whatever reason), there is a $7 product launch that gets mailed around, typically with two OTO's of at least $27 and $47 behind the pay wall. Some of them are dime sales (price goes up with every purchase) so you can monitor volume that way, other's I get data on because of people (big ticket launchers) asking me to push the secondary market surge on (they ask all their bigger SEO affiliates, I'm nothing special) their smaller affiliates in a "they scratched my back, I'll scratch theirs circlejerk".
I never fuck around with the $7 launches + upsell game (lettuce be cereal, it's a lot of work to build out a product, then two more, landers and squeeze pages for it all, put it behind a membership paywall, etc...it's not too much work if it's your bread and butter but it's a lot more work than say outranking Tim Ferris for some thousand dollar commission app building frauduct with a couple hours of setup for an army of SEO tools and VAs) but I'm confident in saying that six days per week, $10k-$50k (and definitely bigger ones when they all team up) launches are going down over there.
Hate the players, hate the game, but the fact of the matter is no small few of those "guru" guys bank harder than 99.9% of WF STS posters. And there's no lack of players in the game that post and lurk here that could confirm what I'm saying, if they felt like publicly outing themselves. Not that I expect you to.
