hello everyone I need help how can I make the game detect if you have already bought something and not let you buy another

----This is the script without the function that I tried to do

local tool = game.ServerStorage.Shop.Tool["Petal Wand"]
local giver = script.Parent
local canGive = false
local price = 50
local function GiveTool(player)
if player.leaderstats.Money.Value < price then return end
canGive = true
player.leaderstats.Money.Value = player.leaderstats.Money.Value - price
local clone = tool:Clone()
clone.Parent = player.Backpack
wait(0.1)
canGive = false
end
giver.ClickDetector.MouseClick:Connect(function(player)
GiveTool(player)
end)

this is the script that with my detection attempt

local tool = game.ServerStorage.Shop.Tool["Petal Wand"]
local giver = script.Parent
local canGive = false
local price = 50
local function GiveTool(player)
	if player.leaderstats.Money.Value < price then
		if not player.Backpack:FindFirstChild(tool.Name) and not player.Character:FindFirstChild(tool.Name) then return end ------- Need Help Here
		canGive = true
	else
		canGive = false
	end --------
	player.leaderstats.Money.Value = player.leaderstats.Money.Value - price
		local clone = tool:Clone()
		clone.Parent = player.Backpack
		wait(0.1)
		canGive = false
	end
giver.ClickDetector.MouseClick:Connect(function(player)
	GiveTool(player)
end)

yes you can buy and equip the object but you can also buy more than 1 and I don’t know how to do that
to make you can only buy 1

		if not player.Backpack:FindFirstChild(tool.Name) and not player.Character:FindFirstChild(tool.Name) then return end ------- Need Help Here
		canGive = true
	else
		canGive = false
	end --------
	
	if canGive == true then
		player.leaderstats.Money.Value = player.leaderstats.Money.Value - price
		local clone = tool:Clone()
		clone.Parent = player.Backpack
		wait(0.1)
		canGive = false
	end

It doesn’t let you buy, I modified it and it still lets you buy more than 1
