News Summary: Considering a drugstore loyalty card

The Associated Press

DEALS APLENTY: All the national drugstore chains — Walgreen Co., Rite Aid Corp. and CVS Caremark Corp. — now offer a free customer loyalty program loaded with incentives. Walgreen, the nation's largest chain, became the latest to offer one when its Balance Rewards program debuted in September.

BENEFITS: The cards offer discounts or chances to earn money or points toward a future purchase. Some also provide ways to consult with a pharmacist or get help for specific conditions like diabetes.

DRAWBACKS: Signing up means consumers sacrifice some privacy. The cards give drugstores a window into your shopping habits.
