St. Louis Dierbergs Markets plans to roll out new pricing on Tuesday for more than 350 generic medications.

Beginning Tuesday, Dierbergs customers will be able to buy 30-day prescriptions for $4 and 90-day prescriptions for $10 from a list of commonly prescribed generic drugs. Greg Dierberg, president of the 23-store chain, said the current economic climate created the right time to introduce the program, which the company began planning late last year.
