Thanks for noticing it! It seems like StepperOnline has stopped selling that model in Aliexpress at this time, but they are still selling it in their website.
What problem do you have with the StepperOnline link? I just tried (I’m also from Spain) and it allowed me to order it to Spain (at least to add it to the cart and proceed with the checkout).
I may be wrong, but maybe are you confusing the warehouse country (China/US/Germany/UK) with the delivery address? hahaha
