I wanted to get the fat cat plush available on the SE store because I like it and there's a sale going on at the moment, but I balked at the extreme shipping cost.

Because the shipping cost to EU countries in the EU store on this €30 plush is a whopping €20.

Except in the UK store it is only £5 and change (with the plush itself at around £25 - in other words currency exchange does not account for this).

What gives? Why is shipping to the rest of the EU so much more expensive than the UK?
