Another good link for the Florence outlet (called The Mall) is as follow: http://www.outlet-firenze.com/index.htm
I've been there several times and it certainly is a place to pick up some bargains. Beware, it's not the easiest place to get to: by train to Reggiello and then a taxi to the outlet; by shared minibus (pick-up at few locations in Florence); or by car. (I used a private cab firm few times and if memory serves me correct their rates are €60 each way. I love shopping at outlets, and there are plentiful in Italy....
