Let's say that I credit an existing regular customer of mine with £10 for goods returned. Refund is not taken - the balance is shown as a credit on their account with me against future purchases. Let's say they now buy items to the value of £25. My cart shows £25 less account balance b/f £10, leaving £15 to pay. How do I show this in PayPal Payment Standard using my own cart? The only way I have been able to do this is to show a £10 discount - but that is not correct - it is not a discount.
It seems to me that it would be helpful if the html variables included a discount_name_cart so that I could have some control over what is displayed (in this case "balance b/f") - and perhaps we should be able to have more than one discount option (what If I also offered a one-off special £2 discount to all orders over £20). Ideally my cart (and PayPal) should show:
Big widget £16
Small widget £9
Discount (£2)
Balance b/f (£10)
Total £13
The only way I seem to be able to do this, currently, is
Big widget £16
Small widget £9
Discount (£12)
Total £13
Any ideas?
