Pharmacy and related departments at Wal-Mart and Sam's Club outlets offer consumers everything they need to maintain their health. In addition to prescription medications and the expert advice that maximizes their effectiveness, the stores carry extensive assortments of over-the-counter health care products. Many of the outlets also include vision centers. Signage touts Wal-Mart's $4 generics program and the retailer's sharp O-T-C pricing.
