Allo BossMini Player

I happened across this

https://www.allo.com/sparky/miniboss-player.html

Nice little package at a very nice price $80 (£62) - almost cheaper than buying the components and putting them all together - easy to swap the Volumio SD for a piCorePlayer version

Then I discovered this

$35 more beacuse we live in Europe WTF !!??

Then I found this full sized Pi based player

and

Again different pricing if you are in Europe.

At the risk of starting a economic or political argument how can this pricing differential exist ?
