Pack an outfit in your hand luggage. If the airport loses your cases you've still got something suitable to wear. It's happened to me before. Jeans and Jordans in 35° weather ain't fun!
I got a great bargain when I bought my Jordan 13's. Less than £100...I got an extra discount from the manager for making him laugh. Its not as good as my Smarty sim though. Been a customer for years and you just cant beat the value!
