Adding a cost reduction to my purchasable items

Question

Hey, this should be pretty simple but am having troubles wrapping my head around it. Basically I am working on a game that has different items that the player can be. One of the premium buys is a price reduction on the items by 5% each time. I'm currently doing this through multiplying by *0.05. The problem with what am doing is that it multiplies the already reduced value by *0.05 on each additional purchase.

this is the sample code i got so far

if (( premiumCoins >= upgradeAmount) && (perkLevel <= 49) )

{

         premiumCoins = premiumCoins - upgradeAmount;
     for (int i = 0; i < 5; i++)
         {
         itemList[i].purchaseCost = itemList[i].purchaseCost - (itemList[i].purchaseCost * 0.05f);
         }

}

Do something like this

 public ItemType[] itemList = new Array[10];
 private ItemType[] costList = new Array[10];
 private float currentDiscount = 1.0f;
 
 void Start()
 {
     costList = itemList;
 }
 
 void AddDiscount(float disc)
 {
     currentDiscount -= disc; // for example discount is 0.05f
 }
 
 itemList[i].purchaseCost = costList * currentDiscount;
