I updated 2 of my calculators today, my Half.com Fee Calculator and my Amazon Marketplace Fee Calculator. On my Half.com calculator I rearranged the user interface to make it a bit more streamlined and I added in a new field for "Actual Shipping Cost". On my Amazon Marketplace calculator, I also streamlined the interface a bit and I improved the "Edit Fees" section. Now "Actual Shipping Cost" and "Amazon Shipping Credit" are visible at all times, it's easier to turn on and off the $0.99 per-transaction fee (if you're a Pro Merchant Subscriber) and it's easier to edit your Closing Fee and Shipping Credit amounts (by default, the calculator will fill these in for you based on your category and shipping method).
