misleading customers

On 11/4/2022 we visited Essenwood pnp. On the brochure it advertise Ricoffy 750g, buy 2 and get the 3rd free. We went to the shelf to see how much the price on Ricoffy were and shelf price was R74.99. We took 3 tins and when scanned the price was R100 per tin, not R74.99 as advertised on shelf. Nowhere did any adverti*****t on the shelf said it is R100 per tin. PicknPay Essenwood misleads customers.
