Problems with PlayerPrefs or something else

So i am a COMPLETE noob at this, i followed a few tutorials on how to make a clicker game and then made the rest by myself. I was trying to make it so the game saves all my stats with playerprefs (money, money per second e.t.c) I got everything to save except some of my upgrade buttons. I couldn't make it so it saves their count or their price. I got it to work on my other upgrade buttons ( the ones that add money per sec), but not for the ones that add money per click ( i tried saving them like i saved my other upgrade buttons, because the code for them is almost identical). I will add the scripts of my buttons ( both types ) and how i save the data. I know i am probably missing something obvious and i'm sorry if i am. Thanks!

Also the game is a joke and that's why some variables are called "depression" :D

The Script Of How I Save And Load The Buttons:

 using UnityEngine;
 using System.Collections;
 
 public class testt : MonoBehaviour
 {
     public Click click;
     public ItemManager[] items;
     public UpgradeManager[] items2;
 
     public void load()
     {
         float olddepression = PlayerPrefs.GetFloat("depression");
         click.depression = olddepression;
 
         int olddpc = PlayerPrefs.GetInt("dpc");
         click.depressionperclick = olddpc;
 
         foreach(ItemManager item in items)
         {
             item.count = PlayerPrefs.GetInt(item.itemName);
         }
 
         foreach (UpgradeManager item in items2)
         {
             item.count = PlayerPrefs.GetInt(item.upgradeName);
         }
 
         foreach (UpgradeManager item in items2)
         {
             item.cost = PlayerPrefs.GetFloat(item.upgradeName + "2");
         }
 
         foreach (ItemManager item in items)
         {
             item.cost = PlayerPrefs.GetFloat(item.itemName + "2");
         }
 
     }
 
     public void save()
     {
         float olddepression = click.depression;
         PlayerPrefs.SetFloat("depression", olddepression);
 
         float olddpc = click.depressionperclick;
         PlayerPrefs.SetFloat("doc", olddpc);
 
         foreach (ItemManager item in items)
         {
             PlayerPrefs.SetInt(item.itemName, item.count);
         }
 
         foreach (ItemManager item in items)
         {
             PlayerPrefs.SetFloat(item.itemName + "2", item.cost);
         }
 
         foreach (UpgradeManager item in items2)
         {
             PlayerPrefs.SetInt(item.upgradeName, item.count);
         }
 
         foreach (UpgradeManager item in items2)
         {
             PlayerPrefs.SetFloat(item.upgradeName + "2", item.cost);
         }
     }
 }

The Script Of The Buttons I Don't Know How To Save:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class UpgradeManager : MonoBehaviour {
 
     public Click click;
     public UnityEngine.UI.Text upgradeInfo;
     public float cost;
     public int count;
     public int clickPower;
     public string upgradeName;
     public Color standart;
     public Color affordable;
     private float baseCost;
     private Slider _slider;
 
     void Start(){
         baseCost = cost;
         _slider = GetComponentInChildren<Slider> ();
     }
 
     void Update() {
         upgradeInfo.text = upgradeName + "\nCost: " + CurrencyConverter.Instance.GetCurrencyIntoString(cost, false, false) + "\nPower: +" + CurrencyConverter.Instance.GetCurrencyIntoString(clickPower, false, false);
 
         if (click.depression >= cost) {
             GetComponent<Image> ().color = affordable;
         } else {
             GetComponent<Image> ().color = standart;
         }
         _slider.value = click.depression / cost * 100;
 
     }
 
     public void PurchasedUpgrade() {
         if (click.depression >= cost) {
             click.depression -= cost;
             count += 1;
             click.depressionperclick += clickPower;
             cost = Mathf.Round (baseCost * Mathf.Pow (1.15f, count));
         }
     }
 
 }
 

The Script Of The Buttons That I Managed To Save:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class ItemManager : MonoBehaviour {
 
     public UnityEngine.UI.Text itemInfo;
     public Click click;
     public float cost;
     public int tickValue;
     public int count;
     public string itemName;
     public Color standart;
     public Color affordable;
     private float baseCost;
     private Slider _slider;
 
     void Start(){
         baseCost = cost;
         _slider = GetComponentInChildren<Slider> ();
     }
 
     void Update(){
         itemInfo.text = itemName + "\nCost: " + CurrencyConverter.Instance.GetCurrencyIntoString(cost, false, false) + "\nDepression: " + CurrencyConverter.Instance.GetCurrencyIntoString(tickValue, false, false) + "/s";
         _slider.value = click.depression / cost * 100;
         if (click.depression >= cost) {
             GetComponent<Image> ().color = affordable;
         } else {
             GetComponent<Image> ().color = standart;
         }
     }
 
     public void PurchasedItem(){
         if (click.depression >= cost) {
             click.depression -= cost;
             count += 1;
             cost = Mathf.Round (baseCost * Mathf.Pow (1.15f, count));
         }
     }
 
 }
