Save values on different objets with same script?

Question

Hello i am making a game like cookie clicker called booty slapper, and in the shop i have different items and when i buy one the price increases and thats working. But the problem is when im trying to save all items with player prefs because i have the same script attached to all the the objects and how can i save all items new price in the playerprefs script? I know how to use Playerprefs with one single object like t$$anonymous$$s:

  PlayerPrefs.SetFloat("currSlaps", gamemanagersc.currSlaps);

but not if i have many items with the same script. My item script:

  public Text CostT;
 
     public float Cost;
     public int modifier;
     
 
   
     public void Update()
     {
         CostT.text = "Cost: " + Cost.ToString("F0");
     }
     public void Buy()
     {
         GameObject gamemanager = GameObject.Find("GameManager");
         gameManager gamemanagersc = gamemanager.GetComponent<gameManager>();
 
         if(gamemanagersc.currSlaps >= Cost)
         {
             gamemanagersc.currSlaps -= Cost;
             gamemanagersc.slapModifier += modifier;
             Cost *= 1.25f;
         }
 
     }

It is the Cost value i want to save.

You can save the cost as a float value in the PlayerPrefs

  PlayerPrefs.SetFloat("Cost", Cost);

Or use somet$$anonymous$$ng like JSON to save your entire object with JsonUtility https://www.youtube.com/watch?v=6uMFEM-napE

@CodeMonkeyYT I get this error: NullReferenceException: Object reference not set to an instance of an object on: GameObject slapmodifier = GameObject.Find("Content"); SlapModifier slapmodsc = slapmodifier.GetComponent();

         slapmodsc.Cost = PlayerPrefs.GetFloat("newcostmod", slapmodsc.Cost);

and:

 GameObject slapssecound = GameObject.Find("Content");
         SlapsPerSecound slapsecsc = slapssecound.GetComponent<SlapsPerSecound>();
 
         PlayerPrefs.SetFloat("newcostsec", slapsecsc.Cost);
         PlayerPrefs.SetFloat("newcostmod", slapmodsc.Cost);

"Content" is inside viewport in a scroll wheel, and inside Content i have put all items with the script
