The one now have The One Basics in Sahara Mall instead of an outlet store...I also got an email about The One Warehouse Sale on Sept 2 at their local distribution centre in Al Quoz.
I think ID Design outlet is on Al Ittihad road (Dubai Sharjah road), near airport. The One used to be in Dubai Outlet Mall, but closed and not sure if it was moved anywhere else. Marina furniture style can be found in Pinky's and Lucky's in Sharjah Industrial Area.
