@Rafi_l ,, I am fairly new to Zen Cart as well, so don't necessarily take my word for it. But Product Attributes will do exactly that. That is what they are for. I know this because I use them on a few of my products. Setting them up is a little tricky, but once you have a particular attribute 'set up', it's not that difficult to add that attribute to a product. I also use Dual Pricing on a different website that I have for retail and Wholesale (wholesale customers are a completely different list of customers from retail), and I don't believe that dual pricing is what you need. Just use attributes.
