I get a VAT refund because I have residency outside the EU. I assume the OP has too.
Rimova knows about the various outlets and doesn't shut anyone down. They are not Louis Vitton. The discount in FRA is offered to air crew only.
No its not the Ringeltaube. That one is only open to LH employees and rarely has good Rimova offers.
If you want cheap LH/Worldshop branded gear, you have to visit the Worldshop outlet in Herford. They usually get things when items in the catalogue are removed.
