CVS Caremark's Maintenance One sounds brilliant -- or is it the makings of an antitrust case? The plan gives Caremark patients access to low mail-order pricing if they fill prescriptions at a CVS.
Competitors say that will encourage Caremark -- the pharmacy benefits side of the business -- to favor CVS. The FTC is investigating.
