Dollar General review: Prices being rang up significantly more at register than marked in store

I have ben shopping at this store for approximately 6 months. I think to myself every time I pay that things aren’t adding up correctly. So last time I was in store I kept my receipt and compared the prices to the advertised price and realized that all 9 items I purchased were rang up higher than advertised. I’m not certain but I’m pretty confident that I have Ben overcharged over $100.00 since I began shopping there. It is a remote store in a booming area for the oil field. (everything is overpriced in the area) but not everything is advertised lower. I shop thwir when I am in town working.
