My issue is this:
We have shirts that people can order, in different designs, different colors. They are screen printed (let's say) on demand.
So, we have multiple "products", but, in fact, the same underlying SKU.
Product 1-Variation 1 is the same as Product 2-Variation 1
(until they are actually printed, same in warehouse).
Does anyone know of a way to manager inventory such that there is a master SKU?
