It's not possible at the moment to use packs and combinations. Why is this? For my purposes, it would be great to be able to do so.
An example:
I sell widgets singly and in packs.
10 single widgets = 1 pack of widgets
I'd like the customer to be able to select on the product page:
( ) 1 Widget
( ) 1 Pack of Widgets (= 10 Widgets)
I can add each of these as individual combinations/attributes. But, then I have to maintain a separate stock for each.
If I have 100 widgets, I would eg need to enter as stock:
50 single widgets
5 widget packs (because 1 pack is 10 single widgets)
If for some reason I sell out of widget packs, I have to manually go into single widget stock, reduce eg by 20 there and add 2 widget packs to the widget pack stock.
According to my understanding of packs, if packs could have combinations, I could have single widgets and then create a pack of these as a second combination, in a way, so that the customer would see:
50 single widgets
5 widget packs (because 1 pack is 10 single widgets)
and the stock of the widget packs would be automatically calculated from the single widgets.
