If you order the Alexander from the German zooplus site
Tierbedarf, Futter, Tiernahrung günstig kaufen bei zooplus it is €79.90 (about £68.30), compared with £89.90 on the UK site. A few people here have done this with no problems. Helpfully, it's set out the same as the UK site so if you open the two side by side it should be straightforward to navigate even in German.
Alternatively, there are a couple of sellers on eBay who sell returned Alexanders from time to time, but there may be some slight damage.
Hope this helps.
