I Am Wondering If Anyone Has Really Made Any $$$ With Zlio?

Okay I saw Zlio mentioned several times in answers about money on yahoo Answers.
So being somewhat cynical I have joined up and opened a pet product store pamperedpup. My kid opened a store to for selling music stuff.
I read a couple of general web reviews from googling information and they didn’t say if they made money only how easy it is to set up… 5 minutes they said…
Well that is true for basic but it takes a lot of work to complete all the modules and add product. I am wondering if it is worth it. I didn’t buy domain name becaues I am not wanting to sink any money in unless it will pay off.
It is already showing up in google which is good – along with lot of other actual websites that sell directly not like (commision of products)
Being cynical I am now wondering if ANYONE has made money from Zlio or a website that is like it?
Thanks for the info.
