Budweiser complaint: Pricing and Rudeness OF eMPLOYEESCASHIERS

On several occasions I have went in to purchase Budweiser Chelada Beer. First the price would be 3.29, and then a week later it was 3.26, but when the cashier rang it up The price was 3.59. I asked and each time i was told that Budweiser delivery person changed the prices and tha I WOULD HAVE TO TAKE IT UP with them. I spoke to the owner that said he didnt change the prices that it was Budweiser delivery person and that he can no override it. I said It is advertised for $3.29, and when I pay for each one that I am charged $3.59 plus tax for each one, and if I purchase 10, I am paying $3.25 or more per purchase of (10). Only out of 1 purchase was I given a refund of ONLY Thirty Cents Total, when overall, I have purchased over 40 items to 80 items that I was only compensated for 1 items, and the cashier slammed .30 cents on the counter and said Is that all you want! I said NO, I want you all to quit overcharging customers, because if you advertise a price, and you charge Thirty Cents to forty five cents more that is illegal The cashier, again blames Budweiser and said it is their responsibility to get the prices in our system right, it is not our responsibility. Again, I said that the sorore owner can make any changes to the prices and that it is his responsibility, not anyone else’s!
