Do you know about affiliate marketing? What about Wealthy Affiliates?

Hi,

I would like to get your experience if you had or have affiliate marketing business online. I happened to find "Wealthy Associate" and it looks good but to get video or more important stuffs, I may need to pay monthly 47 dollars or something. If you have any experience with them, please let me know because I am considering the investment. Just wondering it would be worth paying the fee monthly.

And my wife is starting her new clothing store business very soon. I am trying to help her. I will post my questions about it later.

Thanks in advance for your kind help!
