I want to be able to create a ‘negative coupon’.
e.g. a coupon code that when entered rather than discount all products by 10%, actually increases the products by 10%.
I’ve tested and can see that you can’t add a coupon with a negative value e.g. “10%” so can anyone think of a way to achieve this?
That is, how can I increase the prices for some customers, who are happy to have the higher prices?
Will I need a custom script?
Please don’t discuss why I want to do this, that’s not what I want to discuss, I want to find a way to increase the default pricing for some customers.
