This is just another of many reasons to avoid Wal-Mart. Take your prescriptions and go to an independent pharmacy where the pharmacists and techs know you by name, not as just another dollar in the chain stores. Having a personal realtionship with your pharmacist and techs are of great value and this problem would have been caught very quickly and avoided. DO NOT think for one second you are getting a deal at these chain stores....many, many, many generic drugs cost less than what these stores charge you. These money-grubbers want you to think a $4.00 script is a deal for you....think again....you can get the same script filled and a real drug store for the same price, plus get personalized service. Do the Mom'n'Pop stores a favor and give them your business, after all, they appreciate you and you are a real person not just a number with a dollar.
