I'm not a native English speaker, so I suspect you are right. However, I'm not finding anything here to support your definition: https://en.wikipedia.org/wiki/Product
> In marketing, a product is an object, or system, or service made available for consumer use as of the consumer demand; it is anything that can be offered to a market to satisfy the desire or need of a customer.
This is as close as I get: https://en.wikipedia.org/wiki/Product_(business)
And it says:
> In marketing, a product is an object, or system, or service made available for consumer use as of the consumer demand; it is anything that can be offered to a market to satisfy the desire or need of a customer.
Sounds like something you'd buy?
