I am lost.

I want reward points to be earned against regular priced items not items on sale. So can two items be purchased, one sale item and one regular item and still have it compute reward points correctly?

I want each product to be computed by this equation. PRICE X 0.05

Meaning if you buy something for $100. Your reward points will be $100*0.05. Basically you earn a nickel for every dollar you spend.

I want ... okay enough. Can someone please help set this up?
