Anyone on the forum promote Australian wifi or broadband products? What are your conversion rates like?

I have a wifi site where I've been promoting the Vodafone wireless products and I just hit 500 click throughs but yet to get a single sign up. Pretty disappointing but then again, Vodafone are getting smacked around in the media quite a bit at the moment.

I was expecting on average 1:200 or so but not a single bite. Pulled it all down and replaced with adsense seeing I figured there would be at least a sign up during the xmas period.
