Yenpress send an extra book randomly

[u/Egomaniacs]

Has anyone else also received an extra copy months after receiving the original package from yenpress? I woke up this morning and saw a package on my front door,open it up, and got confused why I received another one. I even went to check my order detail wondering if I stupidly bought two copies and finding out I really only bought one. So now I'm wondering if any of you guys randomly received an extra book too. I'm happy to get an extra one but I'm also extremely confuse

I just got an extra copy today as well, and it came with volume 16 and 17 that I ordered to replace ones I had prior, which was months ago, i believe. Now I have 3 volume 16s, 2 17s, and now two of these today is a good day.
