I'm looking for a single word that describes a part or item being sold. The word should describe the individual items, not the product line, and should make no delineation between different products. It should just mean "an item which we sell, or is sold". Here's a simple example:
You work at a store that sells widgets. There are multiple product lines. You've got your standard widgets and your deluxe widgets. You have multiple stock of each product.
I want to say somethings like the following:
"Check that all the items to be sold are properly packaged"
"Each item to be sold must be tested before going on the shelf"
"Count how many deluxe items to be sold are in stock"
"Product" does not work as it describes the entire product line. "Part" is too vague, as it has too many other meanings, including the same as "product". "Stock" or "Stock item" does not work as it specifically means things which are in inventory.
