i am using Magento 1.9 CE and using some Upsell Products.
I have two Customer Groups - General and Retailer.
Retailer can see and buy all Products. General can see all, but can´t buy all Products.
Now i have some Upsell Items and i want to show them only if the Customer Group can buy them.
Is there any way to do it?. In Magento Enterprise is the Option Rule-Based Product Relations is there anything like that for CE?
Try to override block with Upsells and modify query which fetches data from DB. http://inchoo.net/magento/overriding-magento-blocks-models-helpers-and-controllers/
