Robing the Customers

This happened to me more the once at the same store. I purchase a special eye care solution for scleral lenses form this store every six weeks. it's of the shelf. The price on the shelf reads R87.00 and at the till they charge me R107.00. The explanation give to me on different occasions were 1, teller - that the store has daily price changes and the item was not updated. 2. Till manager - there was a promotion and it is over. 3. Store manager - if the customer queries the price difference then they charge the lower price. Clicks are *********** millions of people daily. This item never goes on promotion. Please all of you reading this, please compare the shelf and till prices when buying from Clicks and tell your friends and family to do the same, or better still do not support stores like Clicks that rob their customers, by charging incorrect prices. Clicks you a *******!
