hello!!

many products are being advertised like sugar, chocolate, cream etc.

and branded products are being advertised

Answer 2

I think the most general term (product) is the only thing that can be used here. The subject of the adverisement is directly related to the business, so in order to apply to all businesses, it would probably need to have a general term like product to apply. You might be able to differentiate based on the use of the product (cleaning products vs lawn products) but even then you'd be narrowing the field and not encompassing a wide range of people. –
