we sell a mailbox:
You can buy the mailbox by itself (no stand or mount).
You can buy the mailbox with a stand.
You can buy the mailbox with a wall mount.
The problem:
woo commerce wants a unique code (SKU) for each variation (the product is a variation product: mailbox alone, mailbox + stand, mailbox + wall mount).
But the stand and wall mount are sold separately too, and you use them with other mailboxes.
What we want:
Track the stock of stands and wall mounts separately and individually.
When someone buys a mailbox with a stand, the purchase should reduce the stand's stock by 1 and the mail box by 1, and when purchased with a wall mount the same should happen with the wall mount stock.
Is there any way of doing this?
