there is one at the premium outlet mall which is exit 68 off of I-4. that is the one I always go to, it is supposed to be better but is always crazy. they have tons of signature stuff! it's the first light past I-4 when you get off, just make a left. you will see a billion people turning most likely.
there is also another coach outlet at the end of International Drive. I think it is exit 73 on I-4. I haven't been to that one though so I don't know anything about it.
definately go and post what you get!! I was there about a week ago and it was amazing.
