To add further value, we have recently introduced a trigger that will instantly update item or repair service price across all stores once it is updated at your default store
To set this up, just:
1. Head to Store Settings of your Main Store.
2. Head to Other Information section.
3. Enable the trigger, "Sync inventory & service item prices on other stores" by selecting Yes from the drop-down menu.
4. Click on Save Changes (button) to implement price sync.
Note: To set same prices, please enable this trigger on your main store. Once enabled, all other store locations will reflect prices of repair and inventory items in main store.
