Unfortenately, there is no 10% discount code available for koffer direkt at the moment. Currently, there is only a 10 Euro coupon available. It is: "koffer27010944". There should be a new 10% coupon available in a couple of days.

On my Blog, you can find the current koffer direkt coupons here:

It is in German, but you just need to press the green button to get the koffer direkt coupon.

You can also check out the discount coupons of Kofferprofi, another German luggage online which also sells Rimowa suitcases:

The store also ships to the US. And shipping fees are with 45 Euro even slightly cheaper than those of koffer direkt.
