Price error print on pamphlet

I am so tired of Spar Vangate Mall that keep having printed errors of there in store specials. Every week a pamphlet gets printed the price is wrong, yesterday i contacted the store and i was told the 2.5kg spar sugar was 26.99 as per pamphlet. Today my sister went inside the store just to tell her it was a misprint and how sorry they are!!! This is unacceptable. I called the store manager by the name of Andy giving me attitude he cant to anything about the error it was a mistake. So frustrated they just lost another loyal customer!!
