Inventory Price Updating

I am trying to get an inventory set up via Syncro, but I’ve been unable to find a way to reflect inventory item price changes, or even a way to link the item to a resource to check it’s current price (Like the items Amazon price). I don’t want to sell something that was $100 when I bought it, but $150 now, without changing the price accordingly.
Let me know if anyone knows a way to do this.
