It’s not a cheap option by any means
Funny, if you told me I could double my leads for $9.95 a month, I'd have kittens. But thankfully I expect most of Wufoo's customers are closer to me than they are to this guy. (Note: if you are developing a SAAS, please don't let yourself be persuaded to price targeting people who would complain that doubling their revenue did not justify $10 a month. Some people just don't pay money for stuff -- fix problems for the people who do.)
