Weis Markets

This morning, Sept.23, 2023 at 9:45 am #177 in Muncy, Pa. I bought meat.
Each package had a sticker buy one get one free and was also reduced from the original price: boneless pork rib $ 2.24 each package (both same price) boneless pork rib $ 2.59 each package (both same price)
London broil $ 5.95 for one other one
London broil $4.57
Also had other purchases that was $ 3.79 for sausage and Turkeyhill ice cream 2 for $ 6.00 and mint tea $ 1.13 those charges were ok
According to my math I should of been charged $ 2.24 + 2.59 + 5.95 + 3.79 + 6.00 + 1.13 = 21.70 but my bill came to $ 31.10 a difference I $ 9.40
