Spar

I was in the Spar Boulevard branch on Saturday 16 January 2021. I saw on there shelfs they had all this H2GLO water packed with the price showing R7.99 so i took 1 of each flavour. At the till it scanned R11.99. I asked for sumone in charge so the cashier called the manageress. I showed her that the price is showing different, then she told me but its a different item. So you tell me if alot of that product is packed next to one another with a price under all of them are you still going to fo check if that is the item on the sticker? Got the pics and receipts all togather as proof wot i am talking about.
