Discount plug in for costumer groups?

Hello

Are there any Discount plug-in that can handle different discount depending on costumer group?
Reason why i am asking is this

Private costumers
Shop for xxx amount and get 10% off
Shop for xxx Amount get 15% off

But  the discount should not apply to other costumer groups

Hello,

Two ways.

1. You can define customer role which you dont want to get discount and use my plugin for same

2. You can define role which you want to give discount and use my other plugin. PM for same.

Thanks,
Jatin

Hello and thank you for answering.

If i read the plug in correct , the costumer must add the coupon code themself when they get above a certain amount?
It is not something you can make automatic on the checkout?

I am looking for instead of the Nopcommerce basic - Customer had spent x.xx amount

i am looking something more like this - Customer are spending x.xx amount and gets xx% discount
togheter with costumer group

Customergroup are spending x.xx amount and gets xx% discount at checkout x2

Customergroup2 are spending x.xx amount and gets xx% discount at checkout

Running on Nopcommerce 3.80

Out of the box there is discount requirement "Must be assigned to customer role"
