There is a great article over at truthaboutcredit.org about the traps credit card companies set out for students. One of the most interesting bits was the success of some of the traps with a free* T-shirt topping the list. They probably would have had to go naked otherwise, so they had to sign up.

The larger point of the article is marketing and business practices of the credit card companies toward students as well as the university's role in the matter. I could attempt to summarize their work, but really, just hit the link and read it for yourselves. They also have additional resources on the right, including a PDF of the full report and one of the major findings.
