Something strange is going on… help me figure this out. :)

I don’t sell on Amazon… never have and definitely don’t currently sell on Amazon. But I do have my own website/online store. Most of my items are unique, but there are a few that *other* sellers sell on Amazon. One is a salt product. Other sellers list it there, but I only have it on my site.

Today I received 4 containers of the salt sent “back” to me from an Amazon distribution center. But they are not my containers of salt. They even have the Amazon inventory stickers on them. But they came to me at my business address with a “Vendor Return” slip return from Amazon in the envelope?!?! How would Amazon even have my business name and address? And this happened once before. I tried contacting Amazon and they had no clue. Just kept telling me I wouldn’t be charged??

At first I thought maybe someone was buying them cheaper on my site and drop shipping them to people, but my site is just a bit higher so that can’t be it.

Any thoughts?
