Business ProfileforCatonsville Shell

I purchased gas at the Shell gas station at *** ********* Road on 11/11. The posted neon lighted sign was 374.9 per gallon. I used my shell discount card to receive .03 cents per gallon. The price I thought I was paying was 371.9. I pumped the gas and noted on my receipt that I was charged 376.9. I went into the "office" and the woman said I should have noted the discrepancy before I started to pump gas. She could not do anything to help me. When I said even without the discount I payed more that the amount posted on the large sign. the woman attendant said the actual price was 379.9 (so I got my three cent discount.) I went back that day and took pictures on my phone of the large sign saying 374.9. Today, November 14, the price of gas at the station is still posted as 374.9. If not noticed, customers can pay several cents more per gallon than posted. The signage, and the pumps (machines) need to be in sync for the price per gallon! . (A complaint was also filed with Shell corporate. I informed the person at corporate customer service that I was also filing a complaint with the Better Business Bureau in Baltimore) I use this gas station to purchase all my gas and have never noted a discrepancy such as this one!
