Shipping Protection —Shipcheck

App works great; the only suggestion I have is to be able to base the cost of protection on a percentage of the product cost. For example, my products range in price from $1 to over $1,000. To charge $5 to protect such an expensive product doesn't seem right. I'd rather set it to charge, say 5% of the total cost instead of a $5 flat rate. Other than that, (and maybe I just didn't find it), the app is fantastic.
