Caution should be exercised because China seller / Shipping from China

I thought I'm doing with this offer a real bargain. The parents of our daughter have already had very good experience with a tube of this type.
I have therefore struck with this offer here, but I had to learn now that this offer will be sent from a seller from China. Not only that this can take weeks and then I have to pick up the shipment from the customs office and any fees such as import tax and customs arise. My warranty I can never in a China seller demand as a German dealer.
Here is definitely bought bought cheaply twice in my opinion + back and forth running around to the customs office. The one must not do that to yourself.
