SARIE MAGAZINE HYPER PRICE INCREASE

Looks like I am unable to add a photograph. The issue is that in January 2018 Sarie magazine sold for R36.50. August's price is R50.00. An increase in price of 37%

My question is where does the justification come from if you consider that SA's inflation rate is less than 5%? Are you affiliated to Eskom? Is the closest I can come to a reason!
