Yes, same product exists on the main Amazon site (amazon.com) but for some reason won’t ship to Germany but will, for example, ship to France. Might depend on how close to a border you are and whether you know someone in the neighbouring country and whether Amazon ships to that country.
No need to be concerned as from
aliexpress.com belonging Price includes VAT (still payable if you do not need it right away, before tomorrow), and that is and calculated as 19% in advance for your particular purchase, every product purchase. No need to worry about particular transport cost/pollution either as most packages will be delivered to Amazon shop(s) anyway. Also, it is not Made in Germany product, punkt.
