A source to see what the purses are for fighters?

I was just about to say that- 7 mil Cotto 1 mil Margo

I have always been interested in what fighters make for big fights (or ballroom/club fights) and what the stipulations are on how much they take home whether they win or lose. In other sports the media throws that info at you immediately. Is there a website that tells you what the purses are for fights? Does anybody know how much cotto or marg took home? Thanks Via Yahoo... Cotto earned a guarantee of $3 million but with his share of the pay-per-view returns, Arum said he likely made $7 million on Saturday for taking a frightful beating. Margarito made a guarantee of $1.5 million “and a whole lot more on pay-per-view,” Arum said.
