Apply discount on store basis

Hi All,
    I am having multiple stores. I am trying to add discount to a product store wise, i.e

I am having
Store Names
"S1"
"S2"

Product Name "P"

I want to add discounts:
1. Product "P" for Store "S1" as 10% discount
2. Product "P" for Store "S2" as 15% discount

and also how to generate coupon store wise?

I am using 3.80 version of Nop.

Can anyone help me out, how to do this?

There's a plugin "Restricted to store" discount requirement rule plugin available from the nopCommerce Team: https://www.nopcommerce.com/p/986/restricted-to-store-discount-requirement-rule-nopcommerce-team.aspx.

I think the rest of what you're asking is covered in the documentation on discounts: http://docs.nopcommerce.com/display/en/Discounts

Thank you so much Petemitch for your prompt response. I have got it working.
