Walgreens was founded in 1901--that should tell you something right there. Shares have taken a beating after Wal-mart announced its perscription plan (Fall '06), and invesotrs are watching the company closely. Although WAG reaps 60% of its profits through prescription sales, a strong growth history indicates that WAG will remain a viable player in the prescription industry.

Publix Supermarkets (not publicly available) generates reports on competitive retail stocks--WAG is second to Publix for 3 years running in its sector.
