Currently we add each month to the previous month in the inventory tab so customers can see how many rounds and how much they paid for each caliber. In addition, add a way to see total amount of accumulated ammunition without adding up every month.
We've reorganized the Inventory Tab so you can now see inventory totals by SKU. This way if you have different grades (9mm Service and Self Defense) you'll see the total for each. Clicking on the summary bar will show the deal for each SKU. This will also work if you are adding other items like Magazines to your account.
