I mean this seriously. What's the catch? People don't give out $50 for something as simple as signing up on a website.

It looks to me like they want you to set up your own storefront selling their (dubious) "health supplements". Apparently, you keep about 40% of the list price. I'll let you guess what that says about their actual margins, the quality of the product as a result, and the realistic chance that you'll make many sales with so much room for someone else to undercut the price- you're a middleman demanding 40%.

They provide no details on that $50 until after you sign up. The FAQ, though, says they pay only in increments of $100. So even with the most charitable interpretation, the catch is obvious: you will get that $50 when and only when you've made an additional $50 of payments due. So you have to set up a site, sell $50 * 10/4 = $50 * 2.5 = $125 of goods, and otherwise qualify for payments (there's always a catch) to get that $50.

So for your $100, you must- at your own expense and effort- set up a web site and make $125 of sales of health supplements of dubious quality and- in some jurisdictions- dubious legality. You don't actually have to handle any product, since you're just an affiliate, but you do have to provide an entry point and keep the user interested.

The odds of doing this successfully are small. The odds that you'll set something up and get a sale or two and forget about it? High enough that the original site is making a hell of a lot of profit off such breakage- people who start accounts, make them some money, but never make enough money to get paid. And I bet you have to go in and ask to actually get money, so if you make a site, set it up, leave it forever (paying hosting fees), and people actually use it but you forget about it, they also keep the money.

They wouldn't give you $50 if they didn't plan to make a heck of a lot more than that, per person they pay out, by doing so. Sketchy as anything, I'd avoid it.
