Incorrect pricing

Browsing through Lego, I came across an item for r1300, stating that there's 2 left. When I add it into my cart, it changes to r1520. I go back, refresh, close browser, open Takealot again, search the item, see that it is still marked at r1300, add it to my cart, and again, it is r1520. I can not get the item at the advertised price! It is ******* to state one price and then charge another!
