Overcharged - Wrong bar codes

<p>I was at Makro Meadowdale/Germiston on 28/04. As I walkd in the entrance I saw a display of Everfresh Long life milk on my left stating 2 x 6L packs for R120. I didn't need milk but the price was good so I took 2 x packs of full cream milk. Having a few items and it being very busy I didn't see all items going through till and only when I got home and looked at my slip did I realise that I was charged R75 for each milk meaning I overpaid by R30. This might not be a lot for people but the advertised price should have been on the system and the hassle of having to drive all the way back there to sort it out etc. the petrol, time is just NOT worth it. However as a customer I am angry that this happened in the first place. Specials and bar codes should match!!!! Basic consumer principles.</p>
