An insider tip to buy really discounted Rimova gear in FRA is the Airliner Shop about 4-5 min away from T1:

They have low prices, give an additional 25% off if you have a airline/airport/crew ID. You can claim the VAT back which is another 19%.

This way I bought a Salsa Deluxe 2 Wheel Cabin Trolley for (309€ -25% - 19%) 194.75€ (aprox 273$)

You can take the bus route 751 and 752 to 'Tor 23' which leave every 10 mins from the arrival level in T1 and then walk the last bit over the bridge.

If that is too complicated for you, there is a guy in FL who sell Rimova over eBay periodically.
