Bayer makes a deal on popular contraceptive with Mark Cuban's online pharmacy

Bayer is the latest name-brand drugmaker to dip its toe into the world of Mark Cuban's online pharmacy, Cost Plus Drugs.

The website offers drugs at steep discounts bypassing middlemen called pharmacy benefit managers. It mostly sells generics, but has been slowly adding brand name products as well.

Yaz birth control pills and Climara, a hormone patch for menopause, will both now be available for a fraction of their list prices, including Cost Plus's standard 15% markup and shipping.
