I've been searching for three days and still have not found suitable answers:

Most items at my site are priced by attribute. I want to display both Retail and Preferred pricing, no matter what the customer's wholesale pricing level.

I'm using radio buttons to display attributes. Currently, the display looks like:
  • Quart ($10.50) (2 lbs.)


What I'd like it to look like is:
  • Quart (2 lbs.)
    Retail: $10.50 Preferred: $8.60


My shop is ZC 1.3.8 with Dual Pricing 1.5.
