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.
