In this 3rd screen you'll set:
- Inventory amounts
- related items
Add related items
If you have any items that this one is related to - or can be used with this one - you would select them here. The drop down menu will be populated with all items entered into your store at this point. You have a total of 5 that you can set as related.
(1) In this example the first 3 options have no limit on inventory - they never run out.
(2) This shows that there are only 2 of each in stock, after that there will be no more available for purchasing until they're reordered.
(3) Since this is the last screen for entering product info all you have to do is click "Save" and this item is finished!
