This extension includes some of the coupons that I have already develop for some sites the list about coupon codes are:
This means that you can apply for example a discount to all the products that have a specific option values if you know a little about Spree you know that an option value can be the size(small, large, extra large, etc) or a color also can be an option value maybe for women or men and now you can give a discount to all the products that include one of those option values that you select from the admin section
Now if you select this new action type 'Set a price for the product' now if the rules for the coupon apply for a product now you can specify the exact price you wan to offer that product or those products
