Consider a rare situation when multiple items sharing the same SKUs are ordered together. In such cases, the app will still sync the stock. 


Let's say you have Product A, Product B, and Product C all sharing the same SKU.


Scenario:
1. Inventory before order: Product A, B, and C all at 10 units.
2. Order placed for 2 of Product A, 2 of Product B, and 3 of Product C (total 7 units)
3. The app will update Products A, B, and C to 3 units.

The app will sync these items even if they are found in the same order. 

Note that there is a chance of overselling if an order contains the same SKU units.
Scenario:
1. Inventory before order: Product A, B, and C all at 2 units.
2. Order placed for 2 of Product A, 2 of Product B, and 1 of Product C (total 5 units.) Oversold.
3. The app will update Products A, B, and C to -3 units.
