Premier cast iron pots and Aluminium stock pots

I have been meaning to buy the premier cast iron pot set, which is a 7 piece set which consist of 3 pots and their lids and a frying pan, the price was R2700.00 . Now to my surprise I want to place order the prices are so high and the set is reduced to 6 piece with the pan selling separately for R450.00. But why did you increase your prices this much while you reduced the set? On The Aluminium stock pots which are now on special of R750.00 they are out of stock. Does this mean the pots will only be available when the sale is over? I am your customer and not I am not happy.
