This store has pricing labels that are inconsistent with what they actually charge you. For instance a beverage that said $1.99 when I got to the register was $3.39. They will also say a product is discounted if you buy two of them and they do not hold true to this statement. They are knowingly misleading people with lower prices on labels so that they will keep their patronage.
Desired outcome: It's blatant false advertising + unacceptable to take advantage of the population that doesn't have the mental facilities to perform arithmetics quickly and accurately
