I tried but those are based by like, cents a day and I never really earned massive cash. Works a lot better for webcomics.
I had that same problem, but the only way to fix that is to set a minimum price, trust me it works. I once set it with no limit and I was making MAYBE 20 cents a day, I set it to $2 or higher bids and I was making about $3.50 a day. Project Wonderful works once you get the hang of it.
