They will try to lure you in with "free" products. Then you find out that to avoid people trying to take advantage of their generosity, you have to pay a "handling fee" that will be refunded to you immediately - an email will be sent telling you how to get your money back... Only when you finally get the email, you find out that you will be given the money off your next purchase from their catalogue! But even worse than that, they do not tell you how to get the money off! Complete con!
