http://www.latimes.com/business/la-fi-internet-ads18-2009nov18,0,1840838.story Just read this, seems like more and more scams are out their these days in the internet marketing industry.
They are already late on taking action against these shady practices. I do online retail and marketing, and even been tricked once into something like this. How on earth, you expect a huge online travel company send your financial information in the background. I think they stopped it already and you have to fill in your credit card info on the landing page now.
