wrong pricing and diffrent prices

Its the 5th clicks we visited in the last month and its shocking how there prices is diffirent at each clicks, they should really look at the barcodes aswell I brought some Usn products at clicks meyersdal and the code show that it cost R89.95 but when I got at the register it wqas suddenly R150 I went to the glen's clicks it was n diffrent price as well even the usn garcinia combogia meyersdal is asking R179 and the glen's one ask R159 and this is not the first time this happens that the price is less on the shelfs but when you go and pay its a lot more from now on I rather go to dischem and know if that's the price on the bar code that's the price I will pay. Also when you busy looking at products the women there doesn't even bother helping you they two busy using up all the testers and when you are looking for a tester its empty or finish and I'm sorry I'm not gonna use the make up there cause if you go there you see them using it straight from the container not even using a ear bud or their finger to put on ther lips and eyes they are even using the products that's close, so much for hygiene..
