If you are looking to negotiate a better price for an item that you might purchase from multiple suppliers then you can run the Item/Vendor statistics report which will show you the quantity of the items that you have purchased from different suppliers. You can specify different dates to filter on. If it’s an important raw material for example this might allow you to go to one supplier and work out a better deal or work out a more constant source of supply.

Here is a quick overview.
