Is there a way I can save this value to a player?

local PurchaseGun = game:GetService("ReplicatedStorage").PurchaseGun
local ReplicatedStorage = game:GetService("ReplicatedStorage")


local GunPrices = {
    ["Pistol"] = 100,
    ["Revolver"] = 300,
    ["Uzi"] = 750
}

PurchaseGun.OnServerEvent:Connect(function(Player, GunName)
    if GunName == "DefaultGun" then
        return
    end
local Cash = Player:FindFirstChild("leaderstats").Cash
if Cash.Value >= GunPrices[GunName] then
        Cash.Value = Cash.Value - GunPrices[GunName]
    local clonegun = ReplicatedStorage.Guns:FindFirstChild(GunName)
local Owned = Player.PlayerGui.Gui.Main.ShopF.ShopF:FindFirstChild(GunName).Owned
Owned.Visible = true
local DisableScript = Player.PlayerGui.Gui.Main.ShopF.ShopF:FindFirstChild(GunName).Script
DisableScript.Disabled = true
local pp = Player.PlayerGui.Gui.Main.PromptPurchase
pp.Visible = false
local Purchased = Player.PlayerGui.Gui.Main.ShopF.ShopF:FindFirstChild(GunName).Purchased
Purchased.Value = 1 -- this is the value I wanna save to the player
local Open =  Player.PlayerGui.Gui.Main.PromptPurchase.Open
Open.Value = 0
        clonegun:Clone().Parent = Player.Backpack
        end
    end)
