How can I improve my trading script?

I am making a simple traiding script, were the player can buy and sell products in different towns. I am using UI buttons and elements for most aktions, but the script is getting really long and it is a lit if work to write all the wariables again and again for every city. Is there a way to improve the code?

Here is my script so far:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class InventoryManager : MonoBehaviour {
     //textelements
     public Text Cointext;
         //playergoods
     public Text sakeplayer;
     public Text fishplayer;
     public Text toolsplayer;
     public Text ironoreplayer;
     public Text woodplayer;
 
     //Player
     public float sake = 0f;
     public float fish = 0f;
     public float tools = 0f;
     public float ironore = 0f;
     public float wood = 0f;
 
     public float coins = 100;
 
     //Town1
     //Produces Sake and Tools needs Wood and Iron
     public float sakeT1; //p
     public float fishT1;
     public float toolsT1; //p
     public float ironoreT1; //n
     public float woodT1; //n
 
     public float sakepriceT1 = 5f;
     public float fishpriceT1 = 10f;
     public float toolspriceT1 = 25f;
     public float ironorepriceT1 = 15f;
     public float woodpriceT1 = 15f;
 
     public float sakesellpriceT1 = 3f;
     public float fishsellpriceT1 = 7f;
     public float toolssellpriceT1 = 15f;
     public float ironoresellpriceT1 = 10f;
     public float woodsellpriceT1 = 10f;
