How do I set up a discount for a particular Customer Group? I can't find it in the documentation.
I tried adding it under the Discount tab on the Product config screen, but when I login to the front end as a member of the relevant Customer Group, I only see the full price, not the price I entered in the Discount tab.
You should do it in the Special tab of product instead of Discount tab. Discount tab is for setting up discount based on quantity of product. Special tab is for setting up the different prices for different customer groups.
Please try again and let me know if it works.
