Order totals in coupon report section

[johnbiggscr]

Having a section in reporting for number of orders that use coupons is great but I need a monetary order total with it as well, not just how much the coupons saved during a particular time period.
So for 2013 it tells me 98 coupons were used and they saved customers $980.....great but did those orders total $1000, $10,000, or $100,000?
