How to create a coupon on specific product or category in Magento?

Question

I am using Magento ver. 1.7.0.2.

Let's say I have 20% off coupon code. This coupon is applicable only to Product B

A customer have in its cart :

• Product A
• Product B
• Product C

I don't want my 20% off coupon apply to other product but only to Product B.

Do you know how I can do that within Magento?

Answer 1

You can create a shopping cart price rule under promotions. Under conditions, you want to choose "product subselection", then under subselection add a rule that the product in the cart must match the sku of the product you want the discount to apply to.
