They didn't pay off their debt. They have $2.6 billion remaining after the partial store buyout from CVS. This is very good for the company because their annual interest payment has greatly decreased. Which could potentially leave room for positive earnings that they desperately need. It will be a hit or miss after the CVS partial buyout. Right now the interest payments alone (on the current 7.8 billion debt load) are eating up RAD profits. But they did not by any means pay off their full debt.
