Using a fake signature will work if they ask for signature. If they're asking for ID, then maybe not. Do you pick up the package, or have it sent to your address? If it's picked up, DNA is much less likely to work.

If you can't DNA, boxing/FTID will work.
Very hit-or-miss, but I used to tell companies that an electronic would leak battery acid, and I had to dispose of it for the safety of my family. Then ask for replacement/refund.

I think I will be going with FTID. Could you please explain further? If I order a service from Germany and I live in a different country, how do I explain the return from somewhere else?

The purpose of FTID is to make it so the company receives and disposes of your package so they have no trace of it. Then, ultimately the tracking will show it was delivered but they won't have any records of it.
If you are completely unaware of the method, either do a lot of research or go for a service that will do it for you.
You can just say that you were on vacation/ business trip and have returned from there. Note that FTID is less likely to succeed if the package crosses international borders.

I am aware of how the method works, kinda. I was just confused about the fact that Amazon will be like "yeah send it back from a different country, that seems legit". I will def be using a FTID service, I am just a bit unsure how to execute it. Is it correct that if it all goes well, I won't even have to say anything to a rep? So like if the package is received and gets lost, they will just refund me auto right?
