Where to get greaseless compounds? Has anyone from the Benelux experience buying them and is anyone else planning to get some?

I think most Americans get them from caswellplating.com but with tax and shipping that could turn out to be pretty expensive.

I also found thepolishingshop.co.uk, closer to home but shipping is still £18.

Bospolijstmaterialen.com I think has greaseless but is a wholesaler.
