If it needs to be returned, it could be difficult though.
If it's damaged they would accept a return I am sure but it would need checking. I think returning just because you don't like it might not be possible.
It's common with newly released cages, that they are available in Europe much sooner than they are in the Uk - because the manufacturer is in Europe. It can often be a year before they become available at Uk stockists. I don't know why, it's just the way it seems to be.
However the fact a German seller is actually shipping to the Uk now is encouraging because for a long time, we couldn't get hold of any cages sold in Germany - there are quite a lot of good cages there from different manufacturers and they stopped shipping to the Uk after Brexit. I believe the customs regulations were just too arduous and expensive. Gradually now, some companies are starting to ship to the Uk again but the prices are much higher due to customs costs presumably so higher import/export charges. Credit to Rodipet who never stopped shipping to the Uk
I can't remember if Getzoo stopped but they are shipping again now. And gradually there is the odd cage available on Zooplus in Germany again, to ship to the Uk (the Barney and 120cm Marrakech) - again at higher prices however.
I don't know which pet companies are doing deals over stocking and selling the Aura - we'll have to wait and see
The Omlet is a "minimum" cage like the Savic Plaza and although there are larger cages, some owners might prefer it. I think the cost of both could put people off now there are a lot more cages and enclosures to choose from. There never seems to be the perfect cage however!
