Message from seller

I recently did DM a seller for a product in the English language, I asked:

"Hello, I'm interested in one of your products. Can you tell me the price of this item?"

the seller is Chinese and replies with:

"But (placeholder for product) is one the producing by factory"

What is meant with this exactly?


It's my guess:

The product is the one produced by the factory.

and I think he wanted you to ask this question from the product owner (for example the factory) or another person! :/
