SmartCoupons: Overwrite coupon value with percentage of product's price
In SmartCoupons you have the option to allow overwriting coupon's amount with Product's Price. (Pick Product's price).
I would like to see an addition. You can enter the percentage of the product's price.
e.g. Product's price = 100
I enter: Pick product's price: 10%
Coupon value will then be 10
