Let me add an additional comment: Yoda was right when she more succinctly said if there was no harm then there are no damages. And, the reason I said NOT to contact CVS is because if you are contemplating legal action, they would be the last ones you would want to contact. However, if you simply want to draw attention to this error, reporting CVS to the Board of Pharmacy with a copy to CVS would certainly be appropriate. The difference in which action to take would depend upon whether or not you plan to litigate.
