I have been getting my Sertraline HCL at the same drug store for 6 months now and I have been paying $ 4.00 because it was on the $ 4.00 list. This month I went in and they wanted to charge me 60 something dollars , then they said 15 dollars and I know I have been paying only 4 dollars and they acted like I was crazy or loosing my mind, they even went as far as to call Walmart and they said that Walmart said it was never on the 4 dollar list of generic drugs? Please someone tell me I' am not loosing my mind. HELP ME IN KENTUCKY...
