Disable discount for group or product

Autodiscount + coupons discount calculation!

I have autodiscount plugin and wanted to check how it works with coupons.

What i need is:

1. Be able to disable autodiscount for some product and/or productgroups, possible? But still discount other product in cart.
2. Not to give additional discount for product that already discounted with coupon but still discount other product with autodiscount

And what i get if i make coupon -20% for some group and have cart with 2 products one ow witch is -20% with coupon. Autodiscount set for 5% over 100EUR, then before COUPON discount is 5 EUR and with coupon it only 4 EUR if COUPONED product costs 20 EUR.

I think it should be 20*0,2=4 - 20-4 = 16 discount with coupon, then if other products >100EUR then discount them for 5%

Could it work like this or no, or am i set up something wrong?

This is essential stuff i believe, as we bought coupon extrafields + audodiscount to have good discount policy!

Aw: Disable discount for group or product

Example of how bad coupon + discount works:

1 item price 100EUR
2 item price 350EUR
COUPON20 - 20% for item 1
Global auto discount >300 EUR - 5%

In cart Item 1 + Item 2 both 1 unit, cart cost - 450 EUR - 5% (22,5 EUR) = 427,5

User have COUPON20 and apply it to cart, what happens NOW:

User gets 350 + 80 for COUPON = 430 cart

BUT he SHOULD get:

100 - 20% coupon discount for item 1 = 80 (and no more discounts)
350 - 5% global discount = 332,5
CART = 332,5 +80 = 412,5

Not possible.

Honestly i think it is some kind of bug that need fixing, it is not very fair that plug-ins dont work as they should.

It is normal that i could group discounts that buyer have, and i bought 2 plug-ins for that...

Shop do not support 2 coupons.

Many addons not works together.

THey should work together, or if they dont' You should leave a comment near every stand alone add on that they DO NOT WORK TOGETHER.

I see big problem that there is not enough description of addons and how do they work, and there is no option to have a demo..
