When previewing an item that you're about to list, it would be a lot more transparent for Folksy to tell you how much they will charge on your bill for listing the item. This is especially pertinent for new customers who read 'First 3 listings are FREE' but add for example 4 items to their first new listing and incur a charge as Folksy's interpretation of First 3 listings are FREE really means first 3 items across listings are FREE.
