Cash given back after purchase?

I am working on a car spawner script that works well except for 1 thing..... The money is given back after the purchase any clue? here is the local script:

script.Parent.MouseButton1Click:Connect(function()

    if script.Parent.Parent.Purchased.Value == true then

            game.ReplicatedStorage.SpawnCar:FireServer(script.Parent.Parent.Name)
        else

        local PriceOfItem = game.ReplicatedStorage:WaitForChild("CheckPrice"):InvokeServer(script.Parent.Parent.Name)

        if game.Players.LocalPlayer.leaderstats.Cash.Value >= PriceOfItem and script.Parent.Parent.Purchased.Value == false then

            game.Players.LocalPlayer.leaderstats.Cash.Value = game.Players.LocalPlayer.leaderstats.Cash.Value - PriceOfItem
            script.Parent.Parent.Purchased.Value = true

    end
    end
end)
