stanton optical would not honor advertised price Evansville Indiana

I called them for a eye appoinment after seeing tv ad free eye exam when buying two pair of eyeglasses for 69 dollars. when i talked with them over the phone they stated lined bifocals was 99.dollars with free eye exam.in the morning i attempted to ask everyone in the store where the 99 dollars glasses were .they all said talk to the sales assoicate ' she told me to go get exam then she would talk to me about glasses. i took my eye exam then asked about the advertised eyeglasses.she said you cannot get that deal you would have to have a coupon printed from my computer.I told her the tv ad mentioned nothing about having a coupon my buy one get one free lined bifcoals ending up costing me 268 since the 99 dollar bifocals were no way they were going to honor advertised price so you will spend more money.the wifes buy one get one free cost 535.00 these people use unethical sales and advertising tectonics to get you in the store this is my first and last time i  will do business with them
