Price you see is not the price you pay. Again

For the second time at Builders warehouse in Kempton Park, have I purchased an item only to find out at the till the price is different to what was displayed. On Sunday 27 Feb 2022 I purchased a Rose shower head marked at R155 on the shelf, but when I paid was R165. I think this is really intentionally done, because they bank on the fact when a customer is paying they wont make an issue of R10. But we are talking about misleading the consumer and according to the consumer act this is *******. Customers really need to be careful when shopping at Builders. Check the prices you are being charged at the till points. I once again made a point of going back in store to take a picture of this. Perhaps time to send to the consumer council
