"Offer not valid for Nine West outlet stores
Please print and present this email instore to receive your discount."
And can probably be used in conjunction with other sales - No guarantees :)
The website is advertising 30% of selected shoes so they should be 55% off using the voucher.
Not sure if you have to actually join Style9 or not, but it can be done online via
the Nine West website http://www.ninewest.com.au
I just received this offer as well!
