Forum OpenACS Q&A: ecommerce: is there a table row for a specific instance of a product?

is there a table that stores a specific product purchased? for example, if someone bought two wigits, would there be a table that has two additional rows because of that?

I'm asking because I want to sell non-shippable stuff, and when ecommerce tells me someone has purchased this product, I make a row in my table with a fk reference to the ecommerce table, so that later if they exchange or refund, I can see the ecommerce table row as well as my table row.
