Good for basic needs but doesn’t deal price inc. nor additional fees

Hi,

I coded a similar plugin to yours and was hoping that yours would help me solve a few missing things in mine regarding taxes and additional fees.

I’m a shop in Europe, and here we always show prices inclusive of taxes. Additionally, the whole concept of my store is to sell products in containers that are returnable/refundable. If you buy a jar of nuts, I’ll charge you 1€, untaxed, that you get back when you return the jar and I update your coupon. We also have two types of taxes over here, 9% for food, 21% for the rest (and I sell both).

I noticed that:

• your coupon applies to the price before taxes, which means that in the front end, people will see that it reduced the price by 5€, but the coupon will only be deduced by like 4.5€.
• it does not apply to additional fees.
• my biggest problem: it applies like regular coupons, which means it lowers the price of each product instead of applying a discount to the final price (like a negative additional fee). Which means that the taxes are also effectively reduced; not a problem for the customer, but a big problem for me because with my whole system of deposit/return that means I’m basically doing tax evasion!

It’s a big issue for me and I’ve been trying to wrap my head around that for months. I know my case is quite specific, but that means I cannot use your plugin.

I also concur with someone else’s suggestion about being able to modify the coupon value manually.

Thank you for your work!
