How do you address changes in costs for inventory items?  Say that I purchased 5 light bulbs at a cost of $3.00, so the value was $15.00.  I sold 3, and ordered 5 more so that I didn't run out, but now the cost of the light bulbs is $4.00.  Now I have 2 @ $3.00, and 4 @ $4.00, so I have a total value of $22.  However, when I update the product, the value is $24.  Is this just not something that QBO can handle?  I did not have this problem when working with QB Desktop.  Thanks!
