[Hikashop] how to set coupon's priority for Multiple Coupons

Hi,

I am using Hikashop with latest AWOcoupon.

I got a problem for Multiple coupons.

Let's say we have a product $100, and there are 2 coupons; coupon_A is to give 20% off, and coupon_B is to give $10 discount.

The problem is:

if the user enter coupon_A firstly and then coupon_B, he will get a price: $100*0.8-$10 = $70

and if coupon_B firstly and then coupon_A, he will get ($100-$10)*0.8 = $72.

I want to provide the user the best price, which means no matter how he enter the coupon, he can always get the lowest price.

could you help to tell me how to do it?

Thanks.

So AwoCoupon processes coupons in the way they are entered.  You can have small control with gift certificates.  So if the $10 discount is a gift certificate, you can go to awocoupon->configuration and under the multiple coupons section, set 'Reorder gift certificates last'.  This will give the best discount.
