Store several buying prices for one product? Variants?
I'd like to create something like a Master Data Management system for our products - first for storing data, not for selling products so much.
We have product X which we can get from supplier 1, supplier 2 and supplier 3.
This should be a reference field I guess?
Now we have several prices from those different suppliers.
Where / how would I store the buying prices?
(Of course I don't want customers to see them - so they should just somehow be associated but not displayed on the site).
