Never heard of it, but I looked it up.

ACCOUNTING TERM: Commingle

In a business context, commingle means to mix together business and personal

items such as assets, cash, expenses, etc.

thanks for that punch drunk

we have a "comingle" recycling bin at work, it has on the outside that you can put paper, plastic, steel cans and Aluminium cans in the one bin.

So, I would imagine co-mingle might mean selling totally different items on the one ID rather than seperate IDs for each type of item.

why do they invent these words anyway?
