I'm looking to buy something from bad dragon but since shipping costs me about 50€ im not really willing to spend that much money. (Since the product is already 90$)

Does anybody know a way to avoid shipping costs somehow or a good alternative to bad dragon?

Neotori. But they have a rather small assortment in comparison to bad dragon.

There's also https://weredog.co.uk/ which is UK based, which has a large collection. Bad Dragon have also apparently invested in them.
