Yes, as I mentioned, I do not have a fixed shipping price (see my initial query: "the amount of shipping for each order will differ").
And, I was hoping that you folks would have addressed this issue, given that some posts from a couple of years ago said it was on the to do list. I'd rather not spend $60 on an extension just for this one thing. That would negate the added sales that I might hope to get from such a coupon.
So, is it still on the todo list to have this built into Hikashop at some point?
