I just bought a pale blue personal Topaz and an Rose A5 Finchley for only 18 Euros together, plus 4.50 euros postage!
Here are a couple of things you should look out for:
Everything is obviously in German, so try to use the automatic translation feature through Google Chrome if you can't read German.
For some reason, when I tried to check out on the Filofax Germany website, it wouldn't accept my existing account login, so I had to make a new one.
When I put my UK address, it said the postcode had to be only numbers. This is because when you choose the UK option for country, it doesn't automatically change the postcode box to accept postcodes with letters in. The way some people have got around this, including me, is to just put the number 0 in instead of an actual postcode. As long as you put the rest of your address, you should be fine.
