I am living in Germany. When I buy a printer via the store, for delivery to my addresse in Germany. Who is my contractual partner ?
You’ll find their authorized partners for Germany listed here:
It’s worth shooting them a question on who’s ensuring the post sales services and warranty in case of… unfortunate need for such services
Your asking a question who’s answer is steeped in contract law. This exceeds the bounds of this forum. Unless one of your Countrymen wants to take a stab at the answer, the answer is highly dependent on your country and in many cases, local laws.
As an example, in the US the answer would be that the seller of record is typically the retailer you purchased it from. In the US that’s Bambu US. However, many states such as California have consumer protection laws that provide greater warranty protections for buyers.
Bottom line is that you will either want to post this in the German section here and let your fellow countrymen reply, or go to reddit Germany and post the question there.
