Perhaps attention deficit disorder led many Wal-Mart's pharmacy staffers to overlook the generic equivalent of Ritalin, methylphenidate, on its list of $4 prescription drugs.
Mrmedsaver.com recently ended up debating a Wal-Mart pharmacist who refused to believe the evidence of the store's own list.
Nonetheless, Wal-Mart does sell 60 tablets of 5 mg and 10 mg each for $4.
Target and Kroger, among other national chains, also offer the drug at the bargain price. According to Consumer Reports, the drug isn't all that expensive even if not included in a $4 plan, though; it found 5 mg tablets for $26 for a 60 pill supply, 10 mg for $31.
