Unfortunately, if you want to buy UAD versions of your native PA plugins, you will have to pay the full retail cost to UA as they are the exclusive retailer of all UAD plugins and it's up to them to create their own discount "crossgrade" policy, and so far they haven't. For future reference, if you ever want to get UAD and Native versions of any PA plugin, buy the UAD version first and then buy the native version. We will give you a special "crossgrade" discount if you already own the UAD version.
