Cant get price from IAP Manager

Hello I have set up IAP manager and sandbox user When I click on the buy button in game it works perfectly. But I am trying to get price in the text. When I check from the unity editor it shows $0.01 in console but text is empty

 public string GetProducePriceFromStore(string id)
 {
   if (m_StoreController != null && m_StoreController.products != null)
         return m_StoreController.products.WithID(id).metadata.localizedPriceString;
     else
         return "";
 
 }

this is for price I did not write it it was already there in IAP Manager.

To get price into the text I use this in start method :

 Coin.text = IAPManager.Instance.GetProducePriceFromStore("Coin_Pack_1").ToString();

id is true if you are going to say that. How can I get price ?
