What's going on with leader prices?

Why when it comes to valuing leaders, say to buy an apparel item, the leader is valued at 500c each but here lately to buy leaders it's usually 650c if you are lucky to 1k-1.5k each? OK so leaders are more sought after now cool np supply and demand, but the other items being bought staying the same amount of leaders? With the raise in value in the defacto dollar why hasn't that had an effect on the goods purchased with said dollar?
